N-Phthaloyl-alanylazide reacts smoothly with trialkyl phosphites producing the corresponding alpha- aminophosphates. With dialkyl hydrogenphosphonates in the presence of benzoyl peroxide, amidophosphates were the isolated products whereas the oxoaziridin-1-yl-phosphonic diamide was preferentially provided from the reaction of the azide with tris(dimethylamino)phosphine. The azide was also allowed to react with alpha-keto-, alpha-ethoxycarbonyl- and alpha-cyanomethylenetriphenylphosphorane to give the corresponding linear disubstituted 1,2,3-triazoles. Screening results of antibiotic potency for the products were discussed in terms of structure-activity relationship (SAR), and an attempt was made to define the structural features for lead compounds.

This communication describes the synthesis of a series of diphosphine NiII(Ph)(CF3) complexes and studies of their reactivity toward oxidatively induced Ph-CF3 bond-forming reductive elimination. Treatment of these complexes with the one-electron outer-sphere oxidant ferrocenium hexafluorophosphate (FcPF6) affords benzotrifluoride, but the yield varies dramatically as a function of diphosphine ligand. Diphosphines with bite angles of less than 92 afforded <10% yield of PhCF3. In contrast, those with bite angles between 95 and 102 formed PhCF3 in yields ranging from 62 to 77%.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2. In a Article，once mentioned of 12150-46-8, Recommanded Product: 1,1-Bis(diphenylphosphino)ferrocene

Intermolecular hydroarylation reactions of highly strained methylenecyclopropanes 2-phenylmethylenecyclopropane (1), 2,2- diphenylmethylenecyclopropane (2), methylenespiropentane (3), bicyclopropylidene (4), (dicyclopropylmethylene)cyclopropane (5), and benzhydrylidenecyclopropane (6) through C-H bond functionalization of 2-phenylpyridine (7 a) and other arenes with directing groups were studied. The reaction was very sensitive to the substitution on the methylenecyclopropanes. Although these transformations involved (cyclopropylcarbinyl)-metal intermediates, substrates 1 and 4 furnished anti-Markovnikov hydroarylation products with complete conservation of all cyclopropane rings in 11-93 % yield, whereas starting materials 3 and 5 were inert toward hydroarylation. Methylenecyclopropane 6 formed the products of formal hydroarylation reactions of the longest distal C-C bond in the methylenecyclopropane moiety in high yield, and hydrocarbon 2 afforded mixtures of hydroarylated products in low yields with a predominance of compounds that retained the cyclopropane unit. As byproducts, Diels-Alder cycloadducts and self-reorganization products were obtained in several cases from substrates 1-3 and 5. The structures of the most important new products have been unambiguously determined by X-ray diffraction analyses. On the basis of the results of hydroarylation experiments with isotopically labeled 7 a-[D5], a plausible mechanistic rationale and a catalytic cycle for these unusual ruthenium-catalyzed hydroarylation reactions have been proposed. Arene-tethered ruthenium-phosphane complex 53, either isolated from the reaction mixture or independently prepared, did not show any catalytic activity. Copyright

Treatment of diphosphines Ph2P(CH2) nPPh2 (n = 1, 2, 4, 6) and [Fe(eta5-C 5H4PR?2)2] (R? = Ph, iPr) with a two-fold excess of (RO)2P(S)N3 (R = Et, Ph) results in the high-yield formation of the N-thiophosphorylated bis(iminophosphorane) derivatives (CH2)n[P{NP(S)(OR) 2}Ph2]2 and Fe(eta5-C 5H4[P{NP(S)(OR)2}R?2]) 2, respectively. The reactions of these ligands with AgSbF 6 in a 1: 1 molar ratio have been investigated. The resulting silver(i) complexes, derived from the selective coordination of the PS units, have been characterized by IR, NMR and MS (FAB) spectroscopy and, in selected cases, by X-ray crystallography. Monomeric, dimeric and polymeric solid-state structures, depending on the nature of the ligand backbone, have been found. The Royal Society of Chemistry 2007.

A novel synthetic route to a 9-phosphatriptycene was developed by utilizing ortho-lithiation of a triarylphosphine oxide as a key step. Systematic comparisons of the NMR spectra of 9-phosphatriptycene derivatives indicated the large s character of the lone pair orbital or the phosphorus-chalcogen bonds of the 9-phosphatriptycene derivatives.

Reference of 50777-76-9. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 50777-76-9, Name is 2-(Diphenylphosphino)benzaldehyde. In a document type is Article, introducing its new discovery.

Mono- and dinuclear oxidorhenium(V) complexes with hemiacetal ligands were isolated from a reaction of (NBu4)[ReOCl4] with a potentially tetradentate Schiff base prepared from (1R,2R)-cyclohexane-1, 2-diamine and (2-formylphenyl)diphenylphosphine in methanol. The hemiacetal is formed by solvolysis of first one imine functionality of the Schiff base, whereas the second remains intact. The resulting amine/iminophosphine coordinates as a tridentate N,N, P ligand in a dinuclear compound. Ongoing degradation of the Schiff base gives more hemiacetal (HL1a) and the final product, the monomeric complex [ReOCl(L1a)2] is formed. Cleavage of the organic framework is not observed during the reaction of (NBu4)[ReOCl4] with a related Schiff base derived from ethylene-1, 2-diamine and (2-formylphenyl)diphenylphosphine. The Schiff base reacts as a bis-bidentate N, P ligand and a dinuclear oxorhenium(V) compound with a central ethylene bridge is formed. Copyright
