2-Phenoxy-1,3,2-diazaphospha-[3]ferrocenophane and related derivatives (oxide, sulfide, selenide) were prepared, characterized in solution by multinuclear magnetic resonance methods (1D and 2D 1H, 13C, 15N and 31/sup

Cyclophosphorylation of 1,8-diaminonaphthalene was accomplished for the first time.Alkyl(aryl) phosphorodichloridites and tetraalkylphosphorodiamidites, which can provide a high yield of tricyclic derivatives, were used as the phosphorylating agents.New diazaphosphorinanes resemble their monocyclic analogs in that they are easily oxidized and easily incorporate smoothly sulfur.X-ray diffraction analysis of ethyl 1,8-naphthylenephosphodiamidite was carried out.The six-membered heterocycle is found to have the envelope conformation with axial location of the ethoxy group.The phosphorus atom is pyramidal (the sum of bond angles at the P atom is 306.2 deg).
