Abstract
A combination of tetrachlorosilane and sodium sulphide in acetonitrile was found to be an efficient thionating reagent for aromatic aldehydes giving the corresponding thioaldehydes as trimers in good yields as well as for α,β-unsaturated ketones under the catalysis of cobalt(II) chloride giving β-mercaptoketones that subsequently auto-oxidized yielding the respective disulfides in moderate yields at ambient temperature. No reaction was observed with aryl methyl ketones.
