Carbotrifluoromethylations of C-C Multiple Bonds (Excluding Aryl- and Alkynyltrifluoromethylations).

Abstract

Organofluorine chemistry has become an expanding area of research in organic chemistry and drug design. The synthesis of fluorine-containing molecules has received high significance in synthetic chemistry. Trifluoromethylative difunctionalizations of carbon-carbon multiple bonds with the simultaneous introduction of a CF3 group and another function have considerable relevance. Because of the high importance of carbon-carbon bond-forming reactions in organic synthesis, carbotrifluoromethylations are considered to be a field of synthetic chemistry of increasing importance. Our current goal in this review is to summarize recent developments of various trifluoromethylation reactions (excluding aryl- and alkynyl-trifluoromethylations) taking into consideration several main approaches, such as alkenyltrifluoromethylation, alkyltrifluoromethylation, carbonyltrifluoromethylation, and cyanotrifluoromethylation reactions.
