Applications of Rozen’s Reagent in Oxygen-Transfer and C–H Activation Reactions
Kuldeep Singh  *, Kulbir Kulbir, Tarang Gupta, Rajneesh Kaur, Raman Singh

Abstract

Rozen’s reagent (hypofluorous acid–acetonitrile complex, HOF·MeCN) is a robust nonspecific oxygen-transfer reagent and became a proven tool for the oxidation of difficult-to-oxidize molecules. It has been applied to instant oxygen transfers to functional groups such as alkenes, alkynes, and aromatic hydrocarbons, epoxidation, oxidation of alcohols, amines, and alkynes, oxygen-transfer reactions with nitrogen, phosphorus, and sulfur-containing substrates, and α-hydroxylation of carbonyl groups. Apart from being a potential green oxidizing agent, the complex has applications in 18O-labeling and C–H functionalization strategies. Recent uses of Rozen’s reagent in developing nanomaterials and oxidized expanded graphite indicate the enormous potential of the reagent.

IYC 2011 : Marie Skłodowska–Curie

The ultimate goal of science is to understand the natural phenomenons and use them for mankind. There is no need to elaborate importance of chemical sciences in society. IYC 2011 gives an opportunity to remember contributions which ultimately changed the world. “Chemistry is often central, with principles and discoveries that enable work in other subjects,”

Marie Skłodowska–Curie

Both women and men have made significant contributions to chemistry. Marie Curie is probably the best-known woman in science. She was the first woman to be awarded a Nobel Prize, first person to win Nobel Prizes in two different scientific disciplines (Nobel Laureate: 1903 in Physics and 1911  in Chemistry). And also, first famous woman scientist in the modern world.  “Mother of Modern Physics” — pioneer in research about . She coined the word “radioactivity” . She was first woman awarded a Ph.D. in research science in Europe, first woman professor at the Sorbonne. She discovered and isolated polonium and radium, and established the nature of radiation and beta rays. Element 96 Curium (Cm) was named in her and Pierre’s honour.

    Book Review : Textbook Of Environmental Studies For Ugc

    Categories UncategorizedPosted on
    Text Book on Environmental Studies
    This book is a part of initiative taken up by UGC and introduces formal study of the environment in our academic curriculum.Considering the deteriorating state of the environment, and as per direction of  the Hon’ble Supreme Court of India, the UGC introduced a basic course on Environmental Studies for undergraduate education.

    The Expert Committee appointed by the UGC looked into all the pertinent questions. This was followed by the framing of the Core Module Syllabus for Environmental Studies for undergraduate courses for all branches of Higher Education. This book is the result of this initiative.
    This book is freely available to download form UGC website

    Atropisomers

    Categories UncategorizedPosted on

      IUPAC Atropisomers is defined as following A subclass of conformers which can be isolated as separate chemical species and which arise from restricted rotation about a single bond, e.g. ortho-substituted biphenyl, 1,1,2,2-tetra-tert-butylethane. The word atropisomer is derived from the Greek a, meaning not, and tropos, meaning turn. The name was coined by Kuhn in 1933, but atropisomerism was first detected in 6,6’-dinitro-2,2’-diphenic acid by Cristie in 1922. References:

    Nomenclature of Inorganic ChemistryIUPAC Recommendations 2005

    This new edition of the ‘Red Book’ clarifies and updates recommendations concerning the names and formulae of inorganic compounds and reflects major recent developments in inorganic chemistry. Moreover, it presents recommendations fully consistent with the principles of the nomenclature of organic chemistry. In order to choose the most appropriate of the various nomenclature systems described, a flowchart is provided to guide the reader to a section or chapter where rules can be found for a particular type of compound or species. Copious examples are supplemented by an extensive subject index.
