Daley, Christopher J. A.; Wiles, Jason A.; Bergens, Steven H. published the artcile< Application of [Ru((R)-BINAP)(MeCN)(1-3:5,6-η-C8H11)](BF4) as a catalyst precursor for enantioselective hydrogenations>, COA of Formula: C6H10O5, the main research area is methyl methylbutanoate methylbutanoic acid enantioselective preparation; acetylphenylalanine enantioselective preparation; methylsuccinic acid methyl ester methylsuccinate enantioselective preparation; citronellol enantioselective preparation; ethyl hydroxybutanoate enantioselective preparation; malic acid methyl ester enantioselective preparation; ruthenium BINAP precursor enantioselective hydrogenation; nonracemic ruthenium BINAP catalyst precursor enantioselective hydrogenation; acetone acetonitrile solvate ruthenium BINAP catalyst; enantioselectivity unsaturated acid hydrogenation triethylamine dependence ruthenium BINAP catalyst; unsaturated ester acid hydrogenation enantioselectivity ruthenium BINAP catalyst; ketone hydrogenation enantioselectivity ruthenium BINAP catalyst; substrate dicarboxylate enantioselectivity hydrogenation ruthenium BINAP catalyst.

A catalyst system employing [Ru((R)-BINAP)(MeCN)(1-3:5,6-η5-C8H11)](BF4) (I) as a catalyst precursor was evaluated using the enantioselective hydrogenations of tiglic acid, α-acetamidocinnamic acid, itaconic acid, Me tiglate, di-Me itaconate, geraniol, Et acetoacetate, and di-Me oxaloacetate as a series of typical substrates. Acetone and MeOH were used as model aprotic and protic solvents, resp. The hydrogenation of substrates containing an α,β-unsaturated carboxylic acid functionality required stoichiometric quantities of NEt3 to occur at reasonable rates in acetone solution, while in MeOH solution it did not. The enantioselectivities were typically higher in acetone than in MeOH. This catalyst system is among the more enantioselective ruthenium-BINAP type systems reported for the catalytic hydrogenation of substrates containing an α,β-unsaturated acid or ester functionality. E.g., the hydrogenation of MeO2CC(:CH2)CH2CO2Me in acetone without Et3N under 4 atm H2 with I gave (S)-MeO2CCH(Me)CH2CO2Me with 100% conversion and in 95% ee. The enantioselectivities for the hydrogenation of ketones ranged from poor (15%) to moderate (74%). 1,4-Dicarboxylate substrates with the prochiral olefin or ketone at the 2-position were all hydrogenated in good to high ee with the same enantioface selectivity both with our system and other catalysts reported in the literature. This raised the possibility that these substrates were hydrogenated through intermediates with similar structural features.

Zhu, Ren-Man;Yang, Cheng-Lin;Chang, Zi-Xuan;Pan, Cai-Yuan;Zhang, Wen-Jian;Hong, Chun-Yan research published 《 Synchronous Synthesis of Polymeric Vesicles with Controllable Size and Low-Polydispersity by Polymerization-Induced Self-Assembly》, the research content is summarized as follows. The size and size distribution of polymeric nanoparticles have great impact on their physicochem. and biol. properties. Polymerization-induced self-assembly (PISA) has been demonstrated to be an efficient method to fabricate various polymeric nanoparticles, among which polymeric vesicles have attracted great interest due to their unique hollow structure. However, polymeric vesicles with relatively broad size distributions and random size are normally formed, which is problematic for many potential applications. Herein, we report the synthesis of polymeric vesicles with low-polydispersity and controllable size by polymerization-induced self-assembly. A mixed macro RAFT agent of three different poly(ethylene glycol) (PEG_m-CPADB) was used to mediate the RAFT dispersion copolymerization of 7-(2-methacryloyloxyethoxy)-4-methylcoumarin (CMA) and benzyl methacrylate (BzMA), which generated vesicles with low-polydispersity (< 0.1) and controllable size in the scope of sub-100 nm. In comparison, RAFT dispersion copolymerization of CMA and BzMA using a single PEG-CPADB as the macro RAFT agent generated vesicles with adjustable but obviously larger size and broader size distributions (> 0.1). The results demonstrate that the ternary stabilizers play a crucial role in the formation of small and low-polydispersity vesicles.

Zhu, Yifan;Jin, Tao;Lian, Tianquan;Egap, Eilaf research published 《 Enhancing the efficiency of semiconducting quantum dot photocatalyzed atom transfer radical polymerization by ligand shell engineering》, the research content is summarized as follows. Manipulating the ligand shell of semiconducting quantum dots (QDs) has proven to be a promising strategy to enhance their photocatalytic performance for small mol. transformations, such as H₂ evolution and CO₂ reduction However, ligand-controlled catalysis for macromols., which differ from small mols. in penetrability and charge transfer behavior due to their bulky sizes, still remains undiscovered. Here, we systematically investigate the role of surface ligands in the photocatalytic performance of cadmium selenide (CdSe) QDs in light-induced atom transfer radical polymerization (ATRP) by using thiol-based ligands with various polarities and chain lengths. A highly enhanced polymerization efficiency was observed when 3-mercapto propionic acid (MPA), a short-chain and polar ligand, was used to modify the CdSe QDs’ surface, achieving high chain-end fidelity, good temporal control, and a dispersity of 1.18, while also tolerating a wide-range of functional monomers ranging from acrylates to methacrylates and fluorinated monomers. Transient absorption spectroscopy and time-resolved photoluminescence studies reveal interesting mechanistic details of electron and hole transfers from the excited QDs to the initiators and 3-MPA capping ligands, resp., providing key mechanistic insight of these ligand controlled and QD photocatalyzed ATRP processes. The thiolate ligands were found to serve as an efficient hole acceptor for QDs, which facilitates the formation of a charge-separated state, followed by electron transfer from the conduction band edge to initiators and ultimately suppressing charge recombination within the QD.
