摘要：

Monohalomalonate carbanions, generated by the 2e- reduction of X2C(CO2Et)2(X = Cl or Br) react with Michael acceptors, giving cyclocondensation products (cyclopropane or dihydrofurane derivatives). The chloro carbanion appears to be more reactive; the reactivity of the bromo carbanion strongly depends on the supporting-electrolyte cation. © 1990.
