Cyclization reactions of vicinal dianions with 1,2-dielectrophiles: synthesis and properties of the first 2,3-diiminothietanes†

Abstract

Reaction of dilithiated ethyl thioglycolate with bis(imidoyl chloride)s of oxalic acid afforded the first 2,3-diiminothietanes, which underwent ring expansion reactions upon treatment with ethyl thioglycolate or dimethyl acetylenedicarboxylate.
