Nickel-catalyzed thiolation of unactivated aryl C-H bonds: efficient access to diverse aryl sulfides

Chem Commun (Camb). 2015 Mar 7;51(19):4069-72. doi: 10.1039/c4cc10446c.

Abstract

A nickel-catalyzed thiolation of unactivated C(sp(2))-H bonds with disulfides employing the PIP directing group was described. This process uses a catalytic nickel catalyst and no metallic oxidants or cocatalysts are required. The reaction tolerates various important functional groups and heteroarenes, providing an efficient synthetic pathway to access diverse diaryl sulfides.
