On the synthesis and coordination properties of N-aryl-substituted 1, 3, 2-diazaphospholidine-4, 5-diimines

New 1, 3, 2-diazaphospholidine-4, 5-diimines were synthesized by condensation of lithiated oxalamidines with PCl3 or PhPCl 2, and characterized by spectral and analytic data. The products react selectively with [(nbd)W(CO)4], [Mo(CO)6], or [(PhCN)2PdCl2] to give stable complexes, in which the heterocycle binds as chelating, bidentate ligand through the nitrogen atoms of the diimine unit. Formation of P-bound or dinuclear complexes was not observed. Reaction with PCl3 or AsCl3 in the presence of SnCl 2 as reducing agent was unspecific. Evidence for the formation of bicyclic products arising from formal [4+1] cycloaddition between the diimine unit and a transient pnictogen(I) species was not obtained, and only a diimine complex of SnCl4 was isolated in moderate yield. Single-crystal X-ray diffraction studies reveal that coordination of the diimine unit induces a substantial structural distortion of the ligand framework, which allows to explain the occurrence of substantial 31P coordination shifts despite the absence of a direct metal-phosphorus bond.

An unconventional synthesis of dibromophosphines

Dibromophosphines, RPBr2, are obtained by reaction of tetrabromomethane with 7-substituted 7-phosphanorbornenes in toluene at ca. 100 °C. The phosphanorbornenes are obtained in situ by cycloaddition of N-phenylmaleimide with 1-substituted 3,4-d

On Organophosphorus Compounds, XXII. 1,2-Diaryl-1,2-dibromodiphosphanes

1,2-Diaryl-1,2-dibromodiphosphanes R(Br)P-P(Br)R 2 (R = C6H5; 4-XC6H4, X = CH3O, F, Cl) were prepared by dehalogenation of RPBr2 with magnesium in a one-batch procedure.While solid 2 presumably consists of only one diastereomer there exists an equilibrium between meso-2, rac-2 and their disproportionation products RPBr2 and (RP)5 in solutions of 2.The influence of temperature, R and solvent on this equilibrium was investigated. - The reaction products of the dissolved phenyl compound 2a correspond to a reaction of its disproportionation products PhPBr2 and (PhP)5, the former preferably reacting on nucleophilic substitution, the latter with electrophilic agents.Under heterogenous conditions diphosphanes Ph(R)P-P(R)Ph can be obtained from 2a and LiR.
