Montmorillonite clays are reported as efficient, inexpensive, and reusable catalysts for carbon–sulfur bond formation by conjugate addition of thiols to α,β-unsaturated ketones/ester/nitrile. The reaction of aryl and aryl alkyl thiols with cyclic/acyclic α,β-unsaturated ketones/ester afforded excellent yields after 5 min to 20 h. The reaction rate was found to be influenced by the (i) size of the ring in case of cyclic enone, (ii) electronic nature of the thiol, and (iii) presence of aryl/alkyl substituent at the β position of the acyclic α,β-unsaturated ketone/nitrile. The conjugate addition of thiols took place at faster rates for five-membered and acyclic α,β-unsaturated ketones than the six-membered analogue. Aryl thiols reacted at fast...
