Metal-free radical selenothiocyanation of terminal and internal alkynes.

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. [ABSTRACT FROM AUTHOR]
