AbstractÐTransmetalation reaction between Z-vinylic tellurides and higher order cyanocuprates generated the corresponding Z-vinylic cyanocuprates. Conjugate addition of these cuprates to enones followed by O-functionalization led to silyl enol ethers, vinyl phosphates and vinyl tri¯ates. The vinyl t

Z-Vinylic higher order cyanocuprates, prepared from the corresponding Z-vinylic tellurides, react efficiently with hindered enones in THF/BF3-Et20 or in diethyl ether. In neat THF the hindered enones fail to react with Z-vinyl cyanocuprates prepared in this way.
