A convenient preparative approach for the synthesis of bis[1-diethoxyphosphorylalkyl]amines
has been developed. Treatment of aromatic aldehydes with ammonia and reaction with
diethyl phosphite gives diethyl aryl[(arylmethylidene)amino]methylphosphonates, which
can be easily reacted with diethyl phosphite in the presence of chlorotrimethylsilane
to give bis[1-diethoxyphosphorylalkyl]amines. This method is easy, rapid, and good-yielding
for the synthesis of bis[1-diethoxyphosphorylalkyl]amines from simple starting materials.
