Vinyl sulfides from thioacetals with copper(I) trifluoromethanesulfonate: ( Z )‐2‐methoxy‐1‐phenylthio‐1,3‐butadiene intermediate: Bis(phenylthio)methane intermediate: 4,4‐ Bis(phenylthio) ‐3‐ methoxy ‐1‐ butene product: (Z)‐2‐ Methoxy ‐1‐ phenylthio ‐1,3‐ butadiene reactant: 3.27 g. [0.00650 mole, 0.0126 g.‐atom of copper(I)] of bis[copper(I) trifluoromethanesulfonate] benzene complex reactant: Thiophenol was purchased from Aldrich Chemical Company, Inc. reactant: Acrolein was purchased by the submitters from Cationics, Division of Columbia Organic Chemicals Company, Inc. (Columbia, South Carolina)

Bei der Reaktion zwischen dem Butadien (I) und Acrylnitril (II) werden die vier isomeren Addukte (III)‐(VI) gebildet, deren Strukturen sichergestellt werden und die in ihren Anteilen in Relation zu den Bedingungen ermittelt werden.
