Palladium(II)-Catalyzed Synthesis of Dibenzothiophenes from 2-Biphenylyl Disulfides by C-H Functionalization.

The palladium-catalyzed oxidative preparation of dibenzothiophene derivatives from 2-biphenylyl disulfides by C-H functionalization is described herein. This procedure shows a high tolerance toward various functional groups and does not require the further addition of a metal oxidant, a base, or a ligand. Also, the present method was applied to the facile preparation of dibenzoselenophene.
