Abstract

4-Chlorophenyl C-(phenylsulfonyl)dithioformate reacts with diazo(trimethylsilyl)methane to form 2-(4-chlorophenylthio)-2-phenylsulfonyl-4,5-bis(trimethylsilyl)-1,3-dithiolan-1-ium(4-chlorophenylthio)(phenylsulfonyl)methylide. It is assumed that this product is formed by [2+3] cycloadditive dimerization of the transient (trimethylsilyl)methanethial S-[(4-chlorophenylthio)(phenylsulfonyl)methylide].
