Dehydrogenative C-H Phenochalcogenazination.

Abstract

Heavy-atom-modified chalcogen-fused triarylamine organic materials are becoming increasingly important in the photochemical sciences. In this context, the general and direct dehydrogenative C–H phenochalcogenazination of phenols with the heavier chalcogens selenium and tellurium is herein described. The latter dehydrogenative C–N bond-forming processes operate under simple reaction conditions with highly sustainable O2 serving as the terminal oxidant.
