Synthesis of Dibenzo[a,e]cyclooctene-5,11(6H,12H)-diones via the Elusive Benzocyclobutenone Anion
Abstract We reported here a facile synthesis of dibenzo[ a , e ]cyclooctene-5,11(6 H ,12 H )-diones via dimerization of benzocyclobutenones in the presence of simple base via the elusive benzocyclobutenone anion. The temperature effect played a crucial role in the dimerization reaction. Further s...
