Progress and recent trends in the direct selenocyanation of (hetero)aromatic C–H bonds

Abstract

This review covers recent advances in the direct selenocyanation of (hetero)aromatic C–H bonds with an emphasis on the reaction mechanisms. This novel approach is an effective means of preparing a variety of aromatic and heteroaromatic selenocyanates, which are extremely versatile synthetic precursors of selenium-containing compounds, such as selenols, seleninic acids, selenides, diselenides, and trifluoromethyl selenides.
