Abstract
Z-Vinylic higher order cyanocuprates, prepared from the corresponding Z-vin ylic tellurides, react efficiently with hindered enones in THF/BF3. Et2O or in diethyl ether. In neat THF the hindered enones fail to react with Z-vin yl cyanocuprates prepared in this way. (C) 1999 Elsevier Science Ltd. All r ights reserved.
