【 摘 要 】

Vinylic tellurides of Z configuration are transformed into higher order Z-vinyl cyanocuprates by transmetallation with higher order lithium dimethyl- or n-butyl(thienyl)cyanocuprates. Reaction of the obtained Z-vinyl cyanocuprates with zinc chloride gives presumably mixed zinc-copper species which react with bromoalkynes leading to enynes and enediynes with retention of the Z double bond configuration.
