A family of N,N-bis(phosphinoylmethyl)amines bearing different substituents on the phosphorus atoms was synthesized by the microwave-assisted and catalyst-free Kabachnik–Fields reaction of (aminomethyl)phosphine oxides with paraformaldehyde and diphenylphosphine oxide. The three-component condensation of N,N-bis(phosphinoylmethyl)amine, paraformaldehyde and a secondary phosphine oxide affording N,N,N-tris(phosphinoylmethyl)amine derivatives was also elaborated. This method is a novel approach for the synthesis of the target products.

Aminophosphine oxides and bis(phosphinoylmethyl)amines were synthesized by the microwave (MW)-assisted Kabachnik-Fields reaction of primary amines, paraformaldehyde and secondary phosphine oxides. The bisphosphines obtained after deoxygenation of the bis(phosphinoymethyl)amine derivatives were utilized in the synthesis of cyclic transition metal complexes.

Tertiary sulfanylphosphine and aminoalkylphosphine oxides can be easily converted into the corresponding tertiary sulfanylphosphine- and aminoalkylphosphine-boranes, respectively, through the facile P=O bond reduction by borane complexes. The easy reduction of the strong P=O bond by BH 3, a mild reducing agent, has been achieved through an intramolecular P=O - B complexation directed by proximal SH or NH activating groups located at the α- or β-position to the P=O bond. A generalized reduction mechanism has been proposed.

4-Aryl and heteroaryl-1(2H)-isoquinolones have been prepared by base promoted cyclization of phosphorylated o-aroyl and heteroaroyl benzamides. Subsequent reduction of the carbonyl and styryl functions of the annulated products has given rise to 4-aryl-1,2,3,4-tetrahydroisoquinolines.
A Convenient Synthetic Route to N-Aryl and N-Alkylamino(alkyl) Phosphonates and Phosphine Oxides

A variety of phosphorylated N-aryl and N-alkyl N-formyl and N-tert-butoxycarbonylaminomethyl derivatives have been efficiently prepared by treatment of the corresponding chloromethyl derivatives with a trialkyl phosphite or an alkyl diphenylphosphinite.These bifunctional compounds may be deprotonated with LDA and further submitted to electrophilic substitution.An acidic treatment of the resulting compounds gives rise to a range of N-aryl and N-alkylamino(alkyl) phosphonates and phosphine oxides.
