In a Article，once mentioned of 13991-08-7, Application In Synthesis of 1,2-Bis(diphenylphosphino)benzene

The synthesis and structure of Rh(I) and Pd(II) complexes of chiral P,C-chelating phosphino-(alpha-sulfinylalkyl)phosphonium ylide ligands with a trisubstituted asymmetric ylidic center P+-CR(S(O)p-Tol)-M (R = alkyl group) have been investigated, and compared to those of the analogous disubstituted ylide complexes (R = H). Reaction of the ethyl onium ylide of o-bis(diphenylphosphino)benzene with (-)-menthyl-(S)-p-tolylsulfinate afforded the corresponding racemic erythro phosphino-(alpha-sulfinylethyl)phosphonium in 90% de (R = Me). The racemization process is interpreted by a Berry-like pseudorotation mechanism driven by the steric repulsion between the alpha-methyl substituent and the bulky menthyloxy S-substituent or sulfur lone pair in the intermediate ylide-sulfinyl adduct. The ylide of phosphino-(alpha-sulfinylethyl)phosphonium reacts with [Rh(cod) 2][PF6] and PdCl2(MeCN)2 to afford the corresponding P,C-chelated threo-Rh(I) and erythro-Pd(II) mononuclear complexes in 70% yield and total diastereoselectivity. These respective complexes act as efficient catalytic precursors for the hydrogenation of (Z)-alpha-acetamidocinnamic acid and allylic substitution of 3-acetoxy-1,3-diphenyl-1-propene with sodium dimethyl malonate. The bonding features of the erythro-Pd(II) complex exhibiting a sulfinyl O…Pd interaction are studied theoretically at the DFT level using ELF and MESP analyses. The eta2-P,C haptomeric form of the ylide ligand is estimated to compete at 19% with the eta1-C haptomeric form dominating at 81%.

We report the copper-catalyzed stereoselective addition of in situ generated chiral boron-alpha-alkyl intermediates to various aldehydes including alpha,beta-unsaturated aldehydes under mild conditions. This tandem and multicomponent method facilitated the synthesis of enantiomerically enriched 1,2-hydroxyboronates bearing contiguous stereocenters in good yield with high diastereo- and enantioselectivity up to a ratio greater than 98:2. In particular, alpha,beta-unsaturated aldehydes were successfully used as electrophiles in Cu?H catalysis through 1,2-addition without significant reduction. The resulting 1,2-hydroxyboronates were used in various transformations.

The aza-Wittig reaction of iminophosphorane N-[o-(triphenylphosphoranylidene)amino]-phenyl pyrrole 4 with heterocumulenes leads to functionalized pyrrolo[1,2-a]quinoxalines. Iminophosphorane 19, derived from 2-(o-amino)phenyl indole, reacts under mild conditions with isocyanates to form 21 which are converted into 5-amino-11H-indolo[3,2-c]quinolines 22. Iminophosphorane 19 also reacts with carbon dioxide and carbon disulfide to give indolo[3,2-c]quinolines 23.

Zirconium-based metal-organic frameworks (Zr-MOFs) based on edge-transitive nets such as fcu, spn, she, csq, and ftw with diverse potential applications have been widely reported. Zr-MOFs based on the highly connected 6,12-connected alb net, however, remain absent on account of synthetic challenges. Herein we report the ligand-directed reticular syntheses and isoreticular expansion of a series of Zr-MOFs with the edge-transitive alb net from 12-connected hexagonal-prismatic Zr6 nodes and 6-connected trigonal-prismatic linkers, i.e., microporous NU-1600, mesoporous NU-1601, and mesoporous NU-1602. These Zr-MOFs exhibit remarkable activities toward the destruction of a nerve agent (soman) and a nerve agent simulant (DMNP).

The reactivity of the sigma,pi-thienyl complex [Fe2(CO)6(mu-Th)(mu-PTh2)] (1) towards a range of phosphines has been studied. With PR3 (R = Ph, Th) carbonyl substitution affords [Fe2(CO)5(PR3)(mu-Th)(mu-PTh2)] (2a-b) as the major product, with smaller amounts of the thienyl-acyl complexes [Fe2(CO)5(PR3)(mu-OC-Th)(mu-PTh2)] (3a-b) resulting from a migratory carbonyl insertion into the thienyl ligand. With diphosphines, thienyl-acyl complexes are the major products in all cases. With dppm, [Fe2(CO)4(mu-dppm)(mu-OC-Th)(mu-PTh2)] (4) results in which the diphosphine bridges the iron-iron bond, while with other diphosphines the chelate complexes [Fe2(CO)4(kappa2-diphosphine)(mu-OC-Th)(mu-PTh2)] (5-9) are isolated, as established through crystallographic studies on [Fe2(CO)4(kappa2-dppe)(mu-OC-Th)(mu-PTh2)] (5) and [Fe2(CO)4(kappa2-dppb)(mu-OC-Th)(mu-PTh2)] (9), both of which show that the diphosphine binds selectively to the oxygen-bound metal centre with phosphorus atoms lying trans to the metal-metal bond and mu-PTh2 bridge. With 1,2-bis(diphenylphosphino)benzene (dppb), [Fe2(CO)5{mu,kappa2-C6H4PPh(C6H4)PPh2}(mu-PTh2)] (10) is isolated in low yields and results from cyclometalation of a phenyl ring and putative elimination of thiophene. In a separate experiment, it has been shown that heating 9 results in the slow formation of 10.

This manuscript consists of two parts which focus on enhancing control over the polymerization of conjugated polymers. In the first part, the controlled chain-growth character of the polymerization of poly(selenophene) using Pd(Ruphos) as a catalyst system is demonstrated. Next, all-conjugated thiophene-fluorene-selenophene triblock-copolymers are synthesized in all possible orders using this catalyst. Subsequent, the properties of these advanced structures are assessed using GPC chromatography and 1H NMR, UV-vis, and fluorescence measurements. DFT calculations were performed to explain the unusual independence of the monomer sequence during the polymerization, traditionally observed in other chain-growth protocols for conjugated polymers.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 787618-22-8 is helpful to your research., Electric Literature of 787618-22-8
