A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1038-95-5, Name is Tri-p-tolylphosphine, molecular formula is C21H21P. In a Article，once mentioned of 1038-95-5, Formula: C21H21P

The distinct reactivity of 1,6-enynes in the presence of a trinuclear metal complex activated by a carboxylic acid is presented. The triplatinum catalyst enables the cyclization of the substrate and subsequent incorporation of a nucleophile in the final product. In contrast, sequential cyclization/double bond shift occurs under analogous conditions in the presence of the corresponding tripalladium complex.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.213697-53-1, Name is 2′-(Dicyclohexylphosphino)-N,N-dimethyl-[1,1′-biphenyl]-2-amine, molecular formula is C26H36NP.

This work reports rhodium catalyzed selective hydroformylation of natural olefins like eugenol, estragole, anethole, prenol and isoprenol using biphenyl based Buchwald phosphine ligands (S-Phos (L1), t-Bu XPhos (L2), Ru-Phos (L3), Johnphos (L4) and DavePhos (L5). Ru-Phos (L3) ligand exhibited high impact on the hydroformylation of eugenol providing high selectivity (90%) of linear aldehyde as major product. In addition, internal natural olefins like anethole and prenol provided moderate to high selectivity (65% and 85% respectively) of branched aldehydes as a major products. The various reaction parameters such as influence of ligands, P/Rh ratio, syngas pressure, temperature, time and solvents have been studied. A high activity and selectivity gained on the way to the linear aldehydes it may be due to the bulky, steric cyclohexyl and isopropoxy groups present in L3 phosphine ligand. Moreover, this catalytic system was smoothly converting natural olefins into corresponding linear and branched aldehydes with higher selectivity under the mild reaction conditions.

Because of the thermodynamic demands of N2 cleavage, N2-derived nitride complexes are often unreactive. The development of multistep N2 functionalization reactions hinges on methods for modulating nitride reactivity with supporting ligands. Here, we describe the reactions of N2-derived Re-nitride complexes, including the first Re nitrides supported by a nitroxide-containing pincer ligand, and unusual examples of Re6+-nitride complexes. The previously reported N2-derived complex (PNP)Re(N)(Cl) (PNP = N(CH2CH2PtBu2)2) can be oxidized by O atom transfer to the backbone amide to form a novel nitroxide-pincer complex or by 1e- to form a rare S = 1/2 Re6+-nitride complex. The Re-nitrido interaction in a series of Re- and ligand-oxidized complexes is characterized using 15N NMR spectroscopy, IR spectroscopy, and DFT calculations, and shows changes in the Re-N bond order from both ligand- and metal-centered oxidations. Chemical oxidation of the supporting ligand to form a nitroxide-pincer ligand results in subtle electronic changes at Re and a more electron-deficient nitride ligand. Combined ligand- and metal-centered oxidation to form a Re6+-nitroxide complex results in a reversal of reactivity at the nitride ligand from nucleophilic to electrophilic. These systematic electronic structure and reactivity studies demonstrate methods for inducing reactivity in N2-derived nitride complexes.

We have presented a near-infrared fluorescent probe Lyso-JN for the detection of nitroxyl (HNO) in cells and in vivo. Lyso-JN is comprised of three moieties: an Aza-BODIPY fluorophore, a HNO-response modulator, diphenylphosphino-benzoyl, and a lysosomal locator, alkylmorpholine. The detection mechanism is based on aza-ylide intramolecular ester aminolysis reaction with HNO. The probe holds the ability to capture lysosomal HNO in RAW 264.7 cells, and it is also successfully employed to visualize HNO in mice. This journal is

Addition of diarylphosphine oxides to the N=N double bond of azobenzenes leads to the formation of the P-substituted hydrazines in up to 98% yield for 24 examples, and the formation of diphenylphosphinic amides was observed in three substrates. This strategy features tolerance of a wide range of functional groups, simple operation, and mild reaction conditions. Specially, this method can be also applied to the gram-scale synthesis of the product. A polar reaction mechanism is also proposed based on control experiments.

Substrate-directed diastereoselective conjugate addition of Gilman cuprates to acyclic enoates has been achieved with the aid of the substrate- bound reagent-directing o-DPPB-group (o-DPPB=ortho-diphenylphosphanyl benzoate). Combining o-DPPB-directed hydroformylation with the o-DPPB- directed cuprate addition provides access to building blocks with up to four stereogenic centers, which may be of relevance for polyketide synthesis. Limit and scope of the o-DPPB-directed cuprate addition of Gilman cuprates with respect to enoate structure as well as control experiments which probe the role of the o-DPPB group are reported.
