Synthesis and properties of heteroaromatic carbenes of the imidazole and triazole series and their fused analogues

Abstract

The present review deals with the syntheses and properties of individual heteroaromatic carbenes of the imidazole, 1,2,4-and 1,2,3-triazole series, their fused analogs and mesoionic carbenes including unprecedented structures such as hyperbasic and hypernucleophilic carbenes. Particular emphasis is placed on their physical properties, novel chemical transformations, and catalytic properties.
