Abstract
Recently, non-diazo carbene precursors have attracted more and more interest because of the apparent safety reason. As one of the most reliable and useful non-diazo carbenoid precursors, enynal/enynone can give rise to furyl- or pyrylium-carbene, which has be applied in a wide range of carbene-transfer reactions, such as cyclopropanation, C-H and X-H insertion, 1,3-dipolar cycloaddition and ylide formation reaction.
Keywords: Carbene, enynal, enynone, cyclopropanation, C-H insertion, X-H insertion.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
