"Click Chemistry" is a chemical concept proposed by Prof. Sharpless in 2001. Notable advantages of click reactions are their high level of efficiency, stereospecificity, atom economy, and functionality tolerances. A large number of examples have been reported in this decade due to the usefulness ...
Chemical reactions occur when two or more substances, called reactants, interact with one another to create one or more new substances as products. Products produced depend on the type of reactants, as well as the conditions surrounding the reaction.Answer and Expl...
摘要: A novel synthesis of the title compounds proceeds via reaction of nitriles with Reformatsky reagent followed by Co(O-Ac)2-catalyzed reaction of the Blaise-type intermediate with a second nitrile.关键词: pyrimidine derivatives multicomponent reactions DOI: 10.1002/chin.201319174 ...

Despite the profound importance of the Wittig reaction and its variants in synthetic chemistry, there still remain mechanistic details which have not been completely elucidated. In some cases, however, structure determinations on intermediates isolated from asymmetric alkenylation reactions have given ...
The highly inspiring work by Professor Norrish has exerted a consistent influence on chemistry and, in particular, on photochemistry, where he was one of the first scientists, along with Gilbert N. Lewis, able to develop a viable concept of excited states and their rate of reaction. However, ...
