✦ Synopsis
Z)-2-Methoxy-l-phenylthio-l.,3-butadienes which are substituted with an alkyl group at the 4-position are not preparable by copper(I)-induced elimination of thiophenol from 4-alkyl-Z-methoxy-l,l-bis(phenylthio)-3-alkenes; a Z-step stereospecific synthesis of one such diene ( ) is described.
Recent work from this laboratory has demonstrated that treatment of certain unsaturated or vinylogous bis(phenylthio)acetals with the benzene complex of copper(I) trifluoromethane-
