Abstract

A Co(II)-catalyzed pyridyl C-H bond carbenoid insertion with α-diazoacetates has been realized. This transformation features a highly regioselective C-C bond formation at the C3-position of pyridines, providing an efficient access to diverse α-aryl-α-pyridylacetates.

2. Frustrated Lewis Pair Catalyzed C-H Activation of Heteroarenes: A Stepwise Carbene Mechanism Due to Distance Effect

Abstract

This study presents new mechanistic insights into the frustrated Lewis pairs (FLPs) catalyzed C–H activation of heteroarenes. Besides the generally accepted concerted C–H activation, a novel stepwise carbene type pathway is proposed as an alternative mechanism. The reaction mechanisms can be varied by tuning the distance between Lewis acid and Lewis base due to catalyst–substrate match. These results should expand the understanding of the structure and function of FLPs for catalyzed C–H activation.
