The document discusses the Wagner-Meerwein rearrangement, a reaction first observed in 1899 where a carbocation is generated followed by a [1,2]-shift of an adjacent carbon-carbon bond to form a new carbocation. This reaction was not fully understood until 1922 when its ionic nature was revealed. The rearrangement involves the migration of hydrogen, alkyl, or aryl groups between carbocations and can involve multiple consecutive shifts. It can be initiated through various means to generate the initial carbocation and the migrating group retains its stereochemistry.4. Wilkinson's Catalyst

N-Bromosuccinimide (NBS) is a source of bromine for radical substitution and electrophilic addition reactions that is easier and safer to handle than bromine. NBS is used for allylic and benzylic brominations, alpha-bromination of carbonyl compounds, and addition reactions to alkenes to form bromohydrins or epoxides. The reactions involve a free radical mechanism initiated by a small amount of bromine radical from NBS.Suzuki reaction

The Suzuki reaction is a palladium-catalyzed cross-coupling reaction between boronic acids or esters with organic halides, triflates, or other boron-containing compounds. This reaction occurs under basic conditions and leads to the formation of carbon-carbon single bonds, typically between an aryl or vinyl group and another aryl or vinyl group. It is commonly used to synthesize biaryl compounds. The reaction proceeds through oxidative addition, transmetallation, and reductive elimination steps. Key advantages are mild reaction conditions and availability of boronic acids.

Wilkinson's catalyst, also known as chloridotris(triphenylphosphane)rhodium(I), is a coordination complex of rhodium with the formula RhCl(PPh3)3. It is a red-brown solid that is soluble in hydrocarbon solvents and used widely as a catalyst for hydrogenation of alkenes. Wilkinson's catalyst is obtained by treating rhodium(III) chloride hydrate with excess triphenylphosphine, which acts as a reducing agent to reduce rhodium from Rh(III) to Rh(I). It adopts a slightly distorted square planar structure and undergoes fast dynamic exchange processes in solution.Diastreoslectivity,chemoslectivity&;regioslectivity crams rule felkin anh m...

Wilkinson's catalyst, chlorotris(triphenylphosphine)rhodium(I), is an organometallic catalyst that is very effective for the homogeneous hydrogenation of unsaturated compounds at room temperature and atmospheric pressure. Its mechanism involves five steps - ligand dissociation, oxidative addition of hydrogen, alkene coordination, migratory insertion, and reductive elimination - known as Tolman's catalytic cycle.

This document discusses ultraviolet-visible (UV-Vis) spectroscopy. It begins by defining spectroscopy and describing the electromagnetic radiation spectrum. It then focuses on UV-Vis spectroscopy, explaining that it involves electronic transitions in molecules caused by the absorption of ultraviolet or visible light. The major electronic transitions that can occur are defined, including *, n *, *, and n * transitions. Factors that affect these transitions, such as conjugation, are also discussed. Real-world examples of molecular structures and the transitions they undergo are provided.Spectroscopy Part-1.pptx

The document discusses various spectroscopic methods used in organic chemistry including UV-Visible, Infrared, Nuclear Magnetic Resonance, and Mass Spectroscopy. It explains the basic principles of spectroscopy such as how electromagnetic radiation interacts with molecules by absorption or emission of energy. The document also provides details on the instrumentation used in spectroscopy including spectrophotometers and spectrographs.

The document discusses green chemistry as a remedy for environmental pollution. It defines green chemistry as the generation of new products and processes that reduce or eliminate hazardous materials. The need for green chemistry is explained by new environmental problems, harmful side effects of some chemicals like DDT, and accidents. Advantages of green chemistry include being eco-friendly, energy efficient, producing less waste and safer products. The principles of green chemistry focus on preventing waste, improving atom economy in synthesis, using safer solvents and feedstocks, and designing for energy efficiency and degradation. Examples are given around safer chemical design and replacing hazardous solvents.Csir net chemistry bits 2

The document discusses chemistry problems and solutions presented by B.Sateesh Kumar, an assistant professor of chemistry at GDC(M)-SKLM. It includes 3 chemistry problems involving the products of reactions and Kumar's explanations of the major products formed. Specifically, it discusses hydrogenolysis to deprotect functional groups on amino acids, the reduction of an epoxide to an alcohol using LAH, and a two-step reaction sequence involving a Schmidt reaction and Boc protection.

Imortance of DIBAL-H
Imortance of DIBAL-HDr Sateesh Kumar Beepala
油
DIBAL-H is a commercially available selective reducing agent that can reduce esters and nitriles to the corresponding aldehydes. It is prepared by heating triisobutylaluminum, which induces beta hydride elimination to form DIBAL-H and isobutene. DIBAL-H selectively reduces esters to aldehydes at low temperatures through a tetrahedral intermediate. Hydrolytic workup of this intermediate then yields the desired aldehyde products. The document provides an introduction to DIBAL-H including its preparation, applications in organic synthesis, and how it differs from other reducing agents like LiAlH4.Recently uploaded (20)

APM event hosted by the South Wales and West of England Network (SWWE Network)
Speaker: Aalok Sonawala
The SWWE Regional Network were very pleased to welcome Aalok Sonawala, Head of PMO, National Programmes, Rider Levett Bucknall on 26 February, to BAWA for our first face to face event of 2025. Aalok is a member of APMs Thames Valley Regional Network and also speaks to members of APMs PMO Interest Network, which aims to facilitate collaboration and learning, offer unbiased advice and guidance.
Tonight, Aalok planned to discuss the importance of a PMO within project-based organisations, the different types of PMO and their key elements, PMO governance and centres of excellence.
PMOs within an organisation can be centralised, hub and spoke with a central PMO with satellite PMOs globally, or embedded within projects. The appropriate structure will be determined by the specific business needs of the organisation. The PMO sits above PM delivery and the supply chain delivery teams.

This presentation delves into the systemic blind spots within pharmaceutical science and regulatory systems, emphasizing the significance of "inactive ingredients" and their influence on therapeutic equivalence. These blind spots, indicative of normalized systemic failures, go beyond mere chance occurrences and are ingrained deeply enough to compromise decision-making processes and erode trust.
Historical instances like the 1938 FD&C Act and the Generic Drug Scandals underscore how crisis-triggered reforms often fail to address the fundamental issues, perpetuating inefficiencies and hazards.
The narrative advocates a shift from reactive crisis management to proactive, adaptable systems prioritizing continuous enhancement. Key hurdles involve challenging outdated assumptions regarding bioavailability, inadequately funded research ventures, and the impact of vague language in regulatory frameworks.
The rise of large language models (LLMs) presents promising solutions, albeit with accompanying risks necessitating thorough validation and seamless integration.
Tackling these blind spots demands a holistic approach, embracing adaptive learning and a steadfast commitment to self-improvement. By nurturing curiosity, refining regulatory terminology, and judiciously harnessing new technologies, the pharmaceutical sector can progress towards better public health service delivery and ensure the safety, efficacy, and real-world impact of drug products.

- 3. Introduction Sodium borohydride structure 1. sodium cyanoborohydride is a colourless salt 2. its chemical formula is NaBH3CN.
- 4. Sodium cyanoborohydride preparation NaBH3CN is less reactive reducing agent than sodium borohydride due to the presence of electron withdrawing cyano group. Preparation :Reaction of NaBH4 with HCN gives NaBH3CN. It is soluble in THF, MeOH, H2O, HMPA and DMF solvents. NaBH3CN cannot reduce the aldehydes (or ) ketones in neutral condition but it reduces the protonated aldehydes and ketones at around pH 3 .
