Cobalt(III)-catalyzed directed C-H coupling with diazo compounds: straightforward access towards extended π-systems

Dongbing Zhao et al. Angew Chem Int Ed Engl. .

Abstract

The first highly efficient and scalable cobalt-catalyzed directed C-H functionalization with carbene precursors is presented. This methodology provides a modular route towards a new class of conjugated polycyclic hydrocarbons with tunable emission wavelengths both in solution and in the solid state.

Keywords: CH activation; carbenes; cobalt; heterocycles; π-systems.
