The reactions of (C9H7)Fe(CO)2R (R = CHMe2, Me) with phosphines and phosphites (L) yield two series of indenyl complexes (C9H7)Fe(CO(COR)(L) via the migratory insertion process.The acyl complexes provide a case of diastereotopic shielding by an asymmetric iron atom.The phosphorus ligands exert electronic effects on the terminal carbonyl group of the methyl complexes that are essentially the same in the indenyl system and in the analogous cyclopentadienyl system.Substitution of methyl for isopropyl in the acyl moiety increases ?-back bonding from iron to carbonyl.The structure of (C9H7)Fe(CO)(COCHMe2)(PPh3) has been determined by X-ray analysis, and exhibits a distorted eta5 coordination of the indenyl ligand .

The ligand electron-donating abilities are compared among a series of monodentate, anionic (phosphino)tetraphenylborate phosphines [Ph4P][Ph2P-R-C6H4BPh3] (R = -C6H4-, -CH2-, -CH2CH2- or none), and their neutral counterparts Ph2PR (R = biphenyl, -CH2Ph, -CH2CH2Ph or Ph). Among the anionic ligands, the position of the tetraphenylborate group relative to the diphenylphosphino donor moiety was systematically varied in an effort to examine how its proximity impacts donor power. The donor power was determined by measuring the 31P-77Se coupling constant for the corresponding selenide of each phosphine ligand via 31P NMR spectroscopy. The anionic ligands yield lower 31P-77Se coupling constants than those measured for their respective neutral counterparts. Moreover, the 31P-77Se coupling constants among the anionic ligands increase when the tetraphenylborate group is positioned further from the phosphorus centre.

Application of 7650-91-1, An article , which mentions 7650-91-1, molecular formula is C19H17P. The compound – Benzyldiphenylphosphine played an important role in people’s production and life.

Our results show that the stereoselectivity of the Wittig-reaction can be controlled by the variation of substituents in accord with the ORDERING CONCEPT OF ALTERNATIV PRINCIPLES (individual pairs, known and unknown classes of alternatives).The “all-phenyl Wittig-system” having three phenyl groups on phosphorous two in ylid- and aldehyd-position was chosen as a standard for our investigations.Differentiation in ylid-position and compensation on phosphorous and aldehyd-position were observed by the comparison of “patterns”.Consequently, most of the selectivity rules of Wittig-reactions can be explained by the differentiation through alternatives in the ylid-position.Inversion or conservation of the “patterns” of measured data points to the variation in structure of starting materials, reaction rates and selectivities.Amount-controls were also described in certain systems.

Identifying potent, selective protein tyrosine phosphatase inhibitors from a library of Au(I) complexes

Therapeutic inhibition of protein tyrosine phosphatase activity is a compelling yet challenging approach to the treatment of human disease. Toward this end, a library of 40 gold complexes with the general formula R 3P-Au-Cl was screened to identify novel inhibitors of PTP activity. The most promising inhibitor obtained for the lymphoid tyrosine phosphatase LYP, (2-pyridine)(Ph2)P-Au-Cl, is one of the most potent and selective LYP inhibitors identified to date with an IC50 of 1.5 ± 0.3 muM, 10-fold selectivity for LYP over PTP-PEST, HePTP, and CD45 in vitro, and activity in cellular studies as well. 2009 American Chemical Society.

Theoretical study on the electronic structures and phosphorescent properties of a series of iridium(III) complexes with the different positional N-substitution in the pyridyl moiety

The geometry structures, electronic structures, absorption and phosphorescent properties of a series of iridium(III) complexes with the different N-substitution cyclometalating ligand and the same benzyldiphenylphosphine auxiliary ligand have been theoretically investigated by using the density functional theory method. The lowest energy absorption wavelengths are located at 378 nm for A, 430 nm for B, 411 nm for C, 436 nm for D, and 394 nm for E. The introduction of N atom substitution at 1-, 2-, 3-, and 4-positions on the pyridyl moiety of complex A leads to an obvious redshifted absorption. The lowest energy emissions for complexes A-E are localized at 450, 409, 438, 483, and 429 nm, respectively, simulated in CH2Cl2 medium at M052X level. Ionization potential and electron affinity have been calculated to evaluate the injection abilities of holes and electrons into these complexes. For complex C, the calculated results showed that it can possibly possess the larger radiative decay rate (kr) value than those of other four complexes. It is anticipated that the theoretical studies can provide valuable information for designing new phosphorescent metal complexes of organic light-emitting diodes.
