Biodegradable choline hydroxide promoted environmentally benign thiolysis of epoxides
An environmentally benign and rapid thiolysis of epoxides using a biodegradable, choline-based task-specific ionic liquid has been developed. The ring opening reaction of aryl and alkyl epoxides proceeded rapidly and afforded the corresponding β-hydroxysulfides in high yields with excellent regioselectivity. The protocol has the advantages of easy work-up, short reaction times, high yields, and a biodegradable catalyst.

LiOH-catalyzed simple ring opening of epoxides under solvent-free conditions
LiOH has been found to be a very simple and selective catalyst for the rapid and mild synthesis of β-hydroxy sulfides and β-hydroxyl nitriles by ring opening of epoxides with aromatic, aliphatic, and heterocyclic thiols and trimethylsilyl cyanide at room temperature under solvent free conditions. All the reactions proceeded satisfactorily in short times and afforded the corresponding products in good to excellent yields with high regioselectivity and chemoselectivity under mild reaction conditions.
