Metal-free radical selenothiocyanation of terminal and internal alkynes

Abstract

We report herein a synthetic strategy for the generation of direct selenothiocyanation from both terminal and internal alkynes via a radical process. Alkynes derived from bioactive molecules, such as L(−)-borneol and L-menthol, are suitable for selenothiocyanation reaction. This method features metal-free conditions and readily available reagents.
