Abstract

Silicon-based thiourea (SiliaBond® Thiourea) (Si-THU), a heterogeneous catalyst, has been applied to the highly selective C\-S bond formation via Michael addition of thiols to a,β-unsaturated carbonyl compounds under solvent-free conditions at 55-60°C. The thio-Michael addition products were obtained in an excellent yield under optimised conditions. This methodology involving a metal-free as well as a metal scavenger catalyst has been found to be an alternative method for the thio-Michael addition reaction.
