Abstract

Treatment of different silylated allenes with hexamethyldisilathiane (HMDST) in the presence of CoCl2· 6H2O affords an easy and high yielding access to α, β-unsaturated thioacylsilanes, which undergo a self-dimerization reaction to afford polyfunctionalized 1, 2- dithiins as the major products.
