A simple preparation of 1H-1,4-diazepine-7(6H)-thiones and their ring contraction to 1-vinyl-2,3-dihydro-1H-imidazole-2-thiones by thermal rearrangement reaction

An efficient synthesis of 1H-1,4-diazepine-7(6H)-thiones via a tandem -cycloaddition-ring expansion of chlorinated 2-aza-1,3-dienes with trimethylsilyl isothiocyanate is described.A thermal rearrangement of these 1,4-diazepine derivatives to 1-viny
