An easy access to α,β-unsaturated thioacylsilanes: a useful route to silylated 1,2-dithiins

Treatment of different silylated allenes with hexamethyldisilathiane (HMDST) in the presence of CoCl 2·6H 2O 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. Reacti...

Summary:Treatment of different silylated allenes with hexamethyldisilathiane (HMDST) in the presence of CoCl 2·6H 2O 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. Reaction of silylated allenes with HMDST affords the generation of unsubstituted thiopropenoylsilanes, which undergo a self-dimerization reaction to silylated 1,2-dithiins.
