摘要：
We present here a clean, solvent-free hydrothiolation of alkynes using solid supported catalyst (Al(2)O(3)/KF). This efficient and improved method selectively furnishes the corresponding anti-Markovnikov vinyl sulfides in good to excellent yields. The method is applicable for aliphatic and aromatic thiols and the catalytic system can be re-used up to two times without previous treatment and with comparable activity. (c) 2008 Elsevier Ltd.
