A novel and convenient method for the synthesis of bis(1-diethoxyphosphorylalkyl) amines has been developed. As described below, treatment of aromatic diimines with diethyl phosphite in the presence of chlorotrimethylsilane gave bis(1-diethoxyphosphorylalkyl)amines. This method is easy, rapid, and good-yielding for the synthesis of bis(1-diethoxyphosphorylalkyl)amines from simple starting materials.
