A copper(I) catalyzed cascadereaction of 2-haloaryl isothiocyanates with isocyanides for the construction of benzo[d]imidazo[5,1-b]thiazoles has been demonstrated. Good to excellent yields could be achieved. This [3+2] cycloaddition and C–S coupling reaction represents an extremely simple way to construct benzo[d]imidazo[5,1-b]thiazoles.

One-pot synthesis of 1,4-dihydro-3,1-benzoxazine-2-thiones by the reaction of 2-lithiophenyl isothiocyanates with aldehydes or ketones
An efficient one-pot method for the synthesis of 4-monosubstituted and 4,4-disubstituted 1,4-dihydro-3,1-benzoxazine-2-thiones has been developed. Treatment of 2-bromophenyl isothiocyantes with butyllithium in THF at −78 °C generates 2-lithiophenyl isothiocyanates, which are allowed to react with various carbonyl compounds, including aldehydes, ketones, and butanolide, to give the corresponding desired
