Abstract
Photolysis of chromium alkoxycarbene complexes in the presence of stabilized ylides produced allenes having effect 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 γ-ket-α,β-unsaturated esters, both in excellent yield
