A new diimine Cu(I) complex, [Cu(DPEphos)(DPOP)]BF4 CH 2Cl2 (1) (DPEphos = bis[2-(diphenylphosphino)phenyl]- ether, DPOP = 2-(11-dipyrido[3,2-a:2′,3′-c]phenazine)-5-p-tolyl-1,3,4- oxadiazole), has been synthesized and characterized by X-ray single-crystal diffraction analysis. In crystals of complex 1, the [Cu(DPEphos)(DPOP)] cations are arranged in supramolecular chains, just like a “zipper”. Cation layers and anion layers are alternating in this structure. The photophysical behavior of DPOP and I was studied.

13406-29-6, Name is Tris(4-(trifluoromethyl)phenyl)phosphine, molecular formula is C21H12F9P, belongs to chiral-phosphine-ligands compound, is a common compound. In a patnet, once mentioned the new application about 13406-29-6, Application In Synthesis of Tris(4-(trifluoromethyl)phenyl)phosphine

An efficient solvent-free synthetic method for the preparation of diphosphonium substituted naphthalenediimide (NDI) radical ions [NDI(PR3)2]+ Br- (R = alkyl/aryl) with excellent yields and ambient stability has been described. A diverse range of trialkyl- and triarylphosphines along with different groups at the axial-positions of the NDI were assessed to verify the efficacy of this new synthetic protocol. A library comprising 24 ambient stable radical ions was synthesized and isolated via solvent-free and conventional heating conditions. The reactions were found to be quite fast and could be completed within 10-20 minutes. In addition, we applied sonication to synthesize the NDI radical ions, when the phosphine reactants exist in the liquid state. Intriguingly, NDI radical ion formation was also observed even on manual grinding of the reactants in a mortar and pestle, although with poor yields. Furthermore, we also realized NDI radical ions in moderate yields by applying ball mill grinding. In addition, we have made an attempt to unearth the most plausible reaction mechanism for these reactions. Importantly, this is the first instance whereby synthetic radical ion chemistry has been brought under the realm of green synthesis. The other significant aspect of our findings is the eco-friendly formation of two consecutive C-P bonds and the in situ one-electron transfer, which can have vital ramifications in organophosphorus and electron transfer chemistry.

Triruthenium dodecacarbonyl-Ru3(CO)12 based diphenylarsino methane-triphenyl phosphine derivatives, such as Ru 3(CO)9-dpam-tris (methyl phenyl) phosphine (1), Ru 3(CO)9-dpam-tris (methoxy phenyl) phosphine (2), and Ru3(CO)9-dpam-tris (fluro phenyl) phosphine (3) are synthesized by two step modified method. The catalytic hydrogenation of cyclohexene, styrene, and phenyl acetylene, on above mentioned Ru-based organometallic catalysts, has been studied under high pressure hydrogen atmosphere. The high pressure hydrogenation of cyclohexene and phenyl acetylene on Complex (1-3), showed good catalytic activity under pressurized condition. Hydrogenation of cyclohexene on Complex (3) showed better (50-65%) conversion in the presence of toluene than hexane solvent. The effect of temperature, role of solvent, and pressure conditions have also been studied.

A new bidentate phosphoramidite (N-Me-BIPAM) based on Shibasaki’s N-linked BINOL was synthesized. This ligand appears to be highly effective for rhodium-catalyzed asymmetric conjugated addition of arylboronic acids to alpha,beta-unsaturated enones. The reaction of ortho-substituted arylboronic acid with acyclic and cyclic enones provides the corresponding products in good yields and enantioselectivities.

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

Reaction of 1-naphthylamine with ethyl benzoylacetate gives the corresponding benzoyl acetamide derivative 1, which undergoes cyclization to 4-phenylbenzo[h]quinolin-2(1H)-one (2) in the presence of H2SO4. Bromination with POBr3, followed by reaction with n-BuLi and DMF, gives 4-phenylbenzo[h]quinoline-2-carbaldehyde (4), which is converted to the corresponding oxime hydrochloride 5 with NH2OH·HCl. Hydrogenation of 5 catalyzed by 10% Pd/C (type 338) leads to 4-phenyl-2-aminomethylbenzo[h]quinoline hydrochloride (HCNNPh·HCl, 6) isolated in high yield. Similarly, the 4-methyl-2-aminomethylbenzo[h]quinoline derivative (HCNNMe·HCl, 12) is prepared starting from 1-naphthylamine and 2,2,6-trimethyl-4H-1,3-dioxin-4-one, following the route for 6. Reaction of RuCl2(PPh3)3 with a diphosphine (PP), the HCl salt 6, and NEt3 in 2-propanol leads to the pincer complexes RuCl(CNNPh)(PP) (PP = Ph2P(CH2)3PPh2, 13; Ph2P(CH2)4PPh2, 14; 1,1?-bis(diphenylphosphino)ferrocene, 15). The methyl derivatives RuCl(CNNMe)(PP) (PP = Ph2P(CH2)3PPh2, 16; Ph2P(CH2)4PPh2, 17; 1,1?-bis(diphenylphosphino)ferrocene, 18) are obtained in a similar way using 12 in place of 6. Treatment of [RuCl2(p-cymene)]2 with rac-BINAP, 6, and NEt3 affords RuCl(CNNPh)(BINAP) (19), isolated as a mixture of two diastereoisomers (3:4 molar ratio). The chiral RuCl(CNNPh)[(S,R)-JOSIPHOS] (20) is obtained as a single isomer from [RuCl2(p-cymene)]2, (S,R)-JOSIPHOS, and 6. Complexes 13-20 efficiently catalyze the transfer hydrogenation of acetophenone in 2-propanol at reflux in the presence of NaOiPr (2 mol%) with S/C = 5000-20-000 and at high rate (TOF up to 6.7 × 103 min-1). With complexes 13, 15, 17, and 18 several ketones of commercial-grade purity have been reduced to alcohols, including the bulky RCO(tBu) (R = Me, Ph) substrates. With 20 acetophenone is reduced to (S)-1-phenylethanol with 85% ee. The pincer complexes 13-15 and 18 are also found highly active in the hydrogenation of ketones at 40 C with an S/C = 10-000, under 5 bar of dihydrogen in methanol and in the presence of 2 mol % of a base (NaOH, KOH, NaOMe).

This chapter describes the rational design and synthesis of semisynthetic lipases by site-directed incorporation of tailor-made peptides on the lipase-lid site to improve its activity, specificity, and enantioselectivity in specific biotransformations. Cysteine was genetically introduced at a particular point of the oligopeptide lid of the enzyme, and cysteine-containing peptides, complementary to the amino acid sequence on the lid site of Geobacillus thermocatenulatus lipase (BTL), were covalently attached on the lid of two different cysteine-BTL variants based on a fast thiol?disulfide exchange ligation followed by desulfurization. The BTL variants were initially immobilized on solid support to introduce the advantages of solid-state chemistry, such as quantitative transformations, easy purification, and recyclability. In the two different immobilized variants BTL-A193C and BTL-L230C, the cysteine was then activated with 2-dipyridyldisulfide to help the disulfide exchange with the peptide, generating the semisynthetic enzyme in high yield. Excellent results of improvement of activity and selectivity were obtained. For example, the peptide?BTL conjugate (at position 193) was 40-fold more active than the corresponding unmodified enzyme for the hydrolysis of per-acetylated thymidine at pH 5, or fourfold in the desymmetrization of dimethyl-3-phenylglutarate at pH 7. The new enzyme also exhibited excellent enantioselectivity in the desymmetrization reaction with enantiomeric excess (ee) of > 99% when compared to that of the unmodified enzyme (ee = 78%).
