摘要

Water promotes hydrothiolation of unactivated alkynes efficiently without any catalyst or additive. The reaction at room temperature furnishes vinyl sulfides with high regioselectivity via anti-Markovnikov addition. The terminal alkynes provide dithiolanes at 80° C by bis- addition. The reactions are very clean and high yielding.
