A general method for the synthesis of symmetric bis(ω-cyanoalkyl)phosphinicacids from ammonium hypophosphite was proposed. The reaction of bis(trimethylsilyl)hypophosphite generated in situ with the ω-bromoalkylnitrile molecule according to the Arbuzov reaction and the subsequent silylation of the hydrophosphoryl intermediate leads to the formation of bis(trimethylsilyl)phosphonite. The latter reacts
