✦ Synopsis

A combination of tetrachlorosilane (TCS) and sodium sulfide in acetonitrile is found to be an efficient thionating reagent for aromatic aldehydes in the absence of catalysis to give the corresponding thioaldehydes as trimers in good yields. Under cobalt(II) chloride catalysis, a,b-unsaturated ketones react with TCS-Na 2 S to give the respective disulfides in good yields via the intermediacy of b-mercaptoketones at ambient temperature.

The enantiospecific preparation of two novel C10-S(II)-and C10-Se(II)-substituted camphor derivatives (arylsulfide and arylselenide) from readily available camphor is described. The established three-step route constitutes a model procedure for the straightforward preparation of interesting enantiop
