Study on the Fluorine-Containing Reactive Intermediates and Their Application in the Organic Synthesis

This review deals with recent progress concerning the preparations, reactions, mechanisms and synthetic applications of some precursor compounds of the fluorine-containing reactive intermediates, such as phenyliodonium bis (perfluoro alkanesulfonyl) methides, PhI+--C(SO2Rf)2; perfluoroalkanesulfonyl azides, RfSO2N3 N,N-dichloro perfluoroalkanesulfonyl amides, RfSO2NCl2, aryldiazonium bis(perfluoro alkanesulfonyl) methides, ArN2 +--CH(SO2Rf)2, aryldiazonium bis(perfluoroalkanesulfonyl) imides, ArN2 +--N(SO2Rf)2 N-sulfinyl per- (or) polyfluoroalkanesulfonyl amides, RfSO2N=S=O, N-sulfinyl per- (or) polyfluorophenylaniline, ArFN=S=O. Under mild reaction conditions they react readily with many organic reagents to give various fluorine-containing products.
