[3-(DIMETHYLAMINO)-2-(TRIFLUOROMETHYL)PROP-2-EN-1-YLIDENE]DIMETHYLAZANIUM HEXAFLUOROPHOSPHATE – EFFICIENT REAGENT FOR THE FORMATION OF TRIFLUOROMETHYL-SUBSTITUTED AZAHETEROCYCLES

Abstract

The microreview presents a comprehensive survey of application of [3-(dimethylamino)-2-(trifluoromethyl)prop-2-en-1-ylidene]dimethylazanium salts as efficient precursors for the synthesis of trifluoromethyl-substituted azaheterocycles. The current state of the art is presented by the most important recent examples (until the end of 2019).
