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].
