The attempted preparation of bis(trifluoromethylsulphanyl)thioketene is described. Mono-and di-(trifluoromethylsulphanyl)-substituted orthothioesters may be prepared fromCH3C(SC2H5)3 and CF3SCl in the presence of anhydrous ZnCl2. The unstable compoundshave been isolated and characterized. The corresponding CF3Se and CF3SO2 derivativesare only formed as intermediates which decompose to ketene diethylmercaptal
