چکیده
The title compound, C(36)H(30)NP(3), a structural isomer of tris-(diphenyl-phosphino)amine, was unexpectedly isolated as the sole phospho-rus-containing product from the reaction of Mg[N(PPh(2))(2)](2)(THF)(2) (THF is tetra-hydro-furan) with CO(2). Its identity was confirmed by (31)P NMR spectroscopy and single-crystal X-ray diffraction. The geometry at the two P(III) atoms is trigonal pyramidal, while the P(V) atom adopts a distorted tetrahedral geometry.

The title compound, C(30)H(27)O(8)P (1), was formed as one of two products {(1) and (2) [Krawczyk et al. (2010 ▶). Acta Cryst. E66 (cv2753)]} in the reaction of dimethyl acetyl-enedicarboxyl-ate with triphenyl-phosphine. The mol-ecule of (1) consists of a five-membered ring, in which the P atom is incorporated. One of the phenyl groups of the triphenyl-phosphine migrated to a vicinal C atom dur...

The title compound, C(42)H(24)N(4)S(4)·2CHCl(3), a symmetrical tetra-thia-fulvalene (TTF) derivative, was prepared by a tri-ethyl-phos-phite-mediated self-coupling reaction of 6,7-diphenyl-1,3-dithia-5,8-diaza-cyclo-penta-[b]napthalen-2-one. The asymmetric unit contains two TTF mol-ecules and four chloro-form solvent mol-ecules. Cl⋯Cl inter-actions [contact distances = 3.263 (1)-3.395 (2) Å] ar...
متن کاملStereospecific S(N)2@P reactions: novel access to bulky P-stereogenic ligands.
The stereospecific hydrolysis of bulky aminophosphine boranes is reported for the first time. The resulting phosphinous acid boranes, upon activation, undergo stereospecific nucleophilic substitution reaction at the phosphorous center with amine nucleophiles. The combination of these two processes provides a novel access to bulky P*-ligands.
