Eliminative deoxygenation: A facile synthesis of α-cyano and α-carboalkoxy substituted vinyl sulfides

The faciIe eliminative deoxygenation of α-cyano and carboalkoxy sulfoxides by trimethylsilyl triflate under mildly basic conditions results in the formation of α-thiophenyl substituted α,β-unsaturated nitriles and esters in high yields. © 1985.
