An efficient combined electrochemical and ultrasound assisted synthesis of imidazole-2-thiones
The electrochemical reduction of 1,3-dialkylimidazolium ionic liquids gave the corresponding N-heterocyclic carbenes that, after reaction with elemental sulfur and ultrasound irradiation, yielded l,3-dialkylimidazole-2-thiones in very high yields. The rea
