Reference of 652-39-1, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 652-39-1, 4-Fluoroisobenzofuran-1,3-dione, introducing its new discovery.
Condensations of stabilized phosphorane 1 with 3-substituted phthalic anhydrides were investigated.The importance of various effects influencing regio- and stereoselectivity of these reactions is discussed.It is proposed that the oxygen atom on the substituents in position 3 can act as a Lewis base toward the electron-deficient phosphorus of the ylid.The resulting complexation stabilizes the transition state for the reacction at the ortho carbonyl group, thus offsetting the usual steric and “push” effects, wich favour attack at the meta carbonyl function. – Key words: Wittig condensations, phthalic anhydrides, regioselectivity, stereoselectivity.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Reference of 652-39-1. In my other articles, you can also check out more blogs about 652-39-1
