摘要

CuII carboxylates dissolved in aq DMF catalyse thermal decomposition of diphenyldiazomethane 1 to afford benzopinacol dicarboxylates 2 in favourable yields. Chelate salts of CuII carboxylates such as salicylate, glycinate or tartrate accelerate thermolysis of 1 affording not 2 but tetraphenylethylene and beneophenone azine. These products are explained by assuming a copper carbenoid. The decomposition of 1 is ...
