Abstract
Transmetalation 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 triflates. The vinyl triflates were transformed into highly unsaturated systems by coupling with alkynes or with Z-vinyl zinc chlorides under Pd (0) catalysis.
