  Synthesis of asymmetricP,P-dialkyl-P?,P?-diphenylethylenediphosphine dioxides

  摘要：

  Asymmetric P,P-dialkyl-P',P'-diphenylethylenediphosphine dioxides were synthesized by the addition of dialkylphosphinous acids to diphenylvinylphosphine oxide in toluene without a catalyst and in DMSO in the presence of concentrated aqueous alkali. The method for isolating dipropyl- and dibutylphosphinous acids obtained by reactions of diethylphosphite with the corresponding alkylmagnesium bromides was improved.
