As a novel extension, the Kabachnik–Fields reaction was applied to the synthesis of alkyl α-aminomethyl-phenylphosphinates, and the double phospha-Mannich reaction was utilized in the preparation of bis(alkoxyphenylphosphinylmethyl)amines. A total of 27 new aminophosphinate derivatives were synthesized by the microwave-assisted solvent-free condensation of alkyl phenyl-H-phosphinates, paraformaldehyde, and primary or secondary amines. The starting P-species were also prepared under microwave conditions. The formation of the N-methylated aminomethyl-phenylphosphinate by-products was also investigated.
