Abstract
The conjugate addition of organozincates derived from ketone alpha,beta-dia nions to enones was examined. Good yields of unsymmetrical 1,6-diketones we re obtained by this reaction. A mixed zincate consisting of the dianion and methyllithium in a 2:1 ratio gave results which were comparable to those o f an unmixed dianion zincate. (C) 2000 Elsevier Science Ltd.
