Asymmetric P,P-dialkyl-P',P'-diphenylethylenediphosphine dioxides were synthesized by the addition of dialyklphosphinous 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. - Key words: ethylenediphosphine dioxides; diphenylvinylphosphine oxide; dialkylphosphinous acids; PH-acids; PH-addition.
