✦ Synopsis

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