The reaction of methylhydrazine with dimethylchlorophosphine in the presence of triethylamine affords the new triphosphine (Me2P)2NâN(Me)(PMe2)1 in near quantitative yields, which represents a bridge between phosphinoamine [>PâN(R)âP<] and phosphanyl hydrazide [>PâN(R)âN(R)âP<]backbones; reaction of 1 with cis-[W(CO)4(NHC5H10)2] proceeds via two coordination modes to give MâPâNâP and MâPâNâNâP metallacyclic frameworks; the structure of the phosphinoamine coordinated part of 1 has been demonstrated by X-ray crystallographic investigation of 2.
