A versatile reactivity from the cage compound P(NMeNMe) 3 P is presented. The Staudinger reaction with Me 3 SiN 3 is carried out. The crystal structure of the compound issued from the reaction on both sides (Me 3 SiN=P(NMeNMe) 3 P=NSiMe 3 ) is reported. When the reaction occurs on only one side, the remaining free phosphorus atom is complexed with RuCl 2 (p-cymene). P(NMeNMe) 3 P reacts with PCl 3 , leading to the heterocyclic compound ClP(NMeNMe) 2 PCl. This heterocycle also displays a versatile reactivity. Substitution reaction with HNiPr 2 leads to * Dr. J.

Comparisons of Phosphorus Ligation Properties in P(CH₂NR)₃P

et al. 2007

Bicyclic P(CH2NMe)3P was synthesized, and its reactions with MnO2, elemental sulfur, p-toluenesulfonyl azide, BH3.THF, and W(CO)5(THF) were shown to furnish a variety of products in which the PC3 and/or the PN3 phosphorus are oxidized/coordinated. In contrast, reactions of the previously known P(CH2NPh)3P with Mo(0) and Ru(II) precursors were shown to afford products in which only the PC3 phosphorus is coordinated. The contrast in reactivity of P(CH2NR)3P (R = Me, Ph) with the aforementioned reagents is discussed in terms of steric and electronic factors. The new compounds are characterized by analytical and spectroscopic (IR, 1H, 31P, and 13C NMR) methods. The results of crystal and molecular structure X-ray analyses of the previously known compounds P(CH2O)3P and P(CH2NPh)3P and 6 of the 14 new compounds obtained in this investigation are presented. Salient features of these structures and the analysis of the Tolman cone angles calculated from their structural parameters are discussed in terms of the effects of constraint in the bicyclic moieties. Evidence is presented for greater M-P sigma bonding effects on coordination of the PC3 phosphorus of P(CH2NR)3P (R = Me, Ph) than are present in PMe3 analogues of group 6B metal carbonyls. From 1JBP data on the BH3 adducts of P(CH2NMe)3P, it is suggested that the free bases MeC(CH2NMe)3P < P(CH2NMe)3P < (Me2N)3P < P(MeNCH2CH2)3N increase in Lewis basicity at the PN3 phosphorus in the order shown. Substantial differences in 31P chemical shifts in the bicyclic compounds discussed herein relative to their acyclic analogues do not seem to be associated with the relatively small bond angle changes that occur around either the PN3 or the PC3 trivalent phosphorus atoms.

Reçule 16 novembre 1981Hexaaza phospha adamantane / Crystal structure / Synthesis Abstract. The title compound C 6 H 15 N 6 P has been synthesized. Its structure has been determined by X-ray single crystal methods. Crystals are monoclinic, space group P2i/n with a = 8.742(11)A, b = 11.342(4)Â, c = 10.209(12)Â, β = 90.28(6)°, Ζ = 4, V = 1012(1)Â 3 , ρ" ρ = 1.3g/cm 3 , ρ χ = 1.32 g/cm 3 , μ(λ) = 2.44cm" \ f(OOO) = 432. There is a C 3 axis in the molecule but not in the crystal. The structure suggests that phosphorus is involved in bonding to adjacent atoms largely via its 3p orbitale and that the lone pair is largely in the 3 s orbital. The pyramidal coordination of the a nitrogen atoms and the relation structure -reactivity is discussed.Dans le cadre d'une étude générale de la réactivité des phosphorhydrazides, des dérivés tricycliques du phosphore tétracoordonné possédant une structure qui s'apparente à celle de l'adamantane ont été synthétisés. χ ρ X = 0 2, X = S 3, X = doublet libre L'analogue à atome de phosphore tricoordonné 3 présentant une faible réactivité par rapport aux dérivés du phosphore tricoordonné à même Brought to you by |
