摘要：

Photolysis of chromium alkoxycarbene complexes in the presence of stabilized ylides produced allenes having electron withdrawing groups on C-1 and electron donating groups on C-3. These highly reactive captodative allenes rearranged to 1,3-substituted-1,3-dienes under mildly acidic conditions and hydrolyzed to gamma-keto-alpha,beta-unsaturated esters, both in excellent yield.
