-
Cyclopropanation of dimethyl maleate with dibromomethane catalyzed by in situ generated Co(0)-or Ni(0)-complex under ultrasonic waves is reported in this paper. The ultrasound accelerates the formation of intermediate complexes:Co(E-H3CO2CH-CHCO2CH3)2(CH3CN)2 and Ni(Z-H3CO2CH=CHCO2CH3)2CH3CN, increases the yield of the reaction product and reduces the reaction time. An adequate method for dimethyl 1,2-cyclopropane-dicarboxylate preparation is described.
