The chemistry of new cyclic phosphorus(III) ligands

A range of new aniline derivatives of tetrakis(hydroxymethyl)phosphonium chloride represented as [P(CH2NHR)4]Cl, where R = phenyl or a substituted phenyl group were synthesised by reacting tetrakis(hydroxymethyl)phosphonium chloride with different aniline precursors in EtOH. Similarly, new phenylenediamine derivatives of tetrakis(hydroxymethyl)phosphonium chloride [P{(CH2NHhRh]Cl, [R = C614, C6H3Me, C6H3COPh, C6H2C414] were synthesised by reacting tetrakis(hydroxymethyl)phosphonium chloride with phenylenediamine precursors. Selected aniline derivatives of tetrakis(hydroxymethyl)phosphonium chloride were reacted with triethylamine in acetone at room temperature to give the corresponding diazaphosphorinane ligands cyclo- {CH2N(R)CH2N(R)CH2-P}-CH2N(H)R , where R = phenyl or a substituted phenyl group. Some of the diazaphosphorinane ligands were reacted with Ru(II), Rh(III), Ir(III) , Pd(lI) and Pt(lI) precursors to form new transition metal complexes... cont'd
