A Convenient Preparation of Arylthioynamines

(2,2,2-Trifluoroethylthio)benzenes prepared from sodium thiolates and 2,2,2-trifluoroethyl p-toluenesulfonate reacted with 3 equiv of lithium dialkylamides in diethyl ether to give arylthioynamines in good yields. The present procedure gives good results with aliphatic sulflde.
