Alkayal, Nazeeha published the artcileWell-defined polyethylene-based graft terpolymers by combining nitroxide-mediated radical polymerization, polyhomologation and azide/alkyne “click” chemistry, Quality Control of 5034-06-0, the publication is Polymer Chemistry (2016), 7(17), 2986-2991, database is CAplus.

Novel well-defined polyethylene-based graft terpolymers were synthesized via the “grafting onto” strategy by combining nitroxide-mediated radical polymerization (NMP), polyhomologation and copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) “click” chem. Three steps were involved in this approach: (i) synthesis of alkyne-terminated polyethylene-b-poly(ε-caprolactone) (PE-b-PCL-alkyne) block copolymers (branches) by esterification of PE-b-PCL-OH with 4-pentynoic acid; the PE-b-PCL-OH was obtained by polyhomologation of dimethylsulfoxonium methylide to afford PE-OH, followed by ring opening polymerization of ε-caprolactone using PE-OH as a macroinitiator, (ii) synthesis of random copolymers of styrene (St) and 4-chloromethylstyrene (4-CMS) with various CMS contents, by nitroxide-mediated radical copolymerization (NMP), and conversion of chloride to azide groups by reaction with sodium azide (NaN₃) (backbone) and (iii) “click” linking reaction to afford the PE-based graft terpolymers. All intermediates and final products were characterized by high-temperature size exclusion chromatog. (HT-SEC), Fourier transform IR spectroscopy (FTIR), proton NMR spectroscopy (¹H NMR) and differential scanning calorimetry (DSC).

Wawrzynczak, Agata published the artcileHydrosilylation of n-alkenes and allyl chloride over platinum supported on styrene-divinylbenzene copolymer, Safety of Dichloro(methyl)(octyl)silane, the publication is Catalysis Today (2011), 169(1), 69-74, database is CAplus.

Catalytic performance of styrene-divinylbenzene copolymer-supported platinum catalyst of high crosslinking degree and high surface area was studied in reactions of hydrosilylation of allyl chloride, 1-octene and 1-butene. The catalyst has shown considerably greater stability of catalytic activity than classical active carbon-supported catalyst. In experiments on repeated use of catalysts, the decrease in catalytic activity for hydrosilylation of liquid double bond-containing compounds proceeding in the presence of the copolymer-supported and carbon-supported platinum was considerably smaller in the case of the former catalyst. Bimetallic Pt-Cu catalyst on polymeric support appeared to be considerably less active than monometallic catalyst.

Cid, Jose Maria published the artcileDiscovery of 1,4-Disubstituted 3-Cyano-2-pyridones: A New Class of Positive Allosteric Modulators of the Metabotropic Glutamate 2 Receptor, Category: chlorides-buliding-blocks, the publication is Journal of Medicinal Chemistry (2012), 55(5), 2388-2405, database is CAplus and MEDLINE.

The discovery and characterization of compound 48, a selective and in vivo active mGlu2 receptor pos. allosteric modulator (PAM), are described. A key to the discovery was the rational exploration of the initial HTS hit 13 guided by an overlay model built with reported mGlu2 receptor PAM chemotypes. The initial weak in vitro activity of the hit 13 was quickly improved, although compounds still had suboptimal druglike properties. Subsequent modulation of the physicochem. properties resulted in compounds having a more balanced profile, combining good potency and in vivo pharmacokinetic properties. Final refinement by addressing cardiovascular safety liabilities led to the discovery of compound (I). Besides good potency, selectivity, and ADME properties, I displayed robust in vivo activity in a sleep-wake EEG (sw-EEG) assay consistent with mGlu2 receptor activation, in accordance with previous work from our laboratories

Despite the widespread application of hypervalent iodines, the corresponding λ³-bromanes are less explored. Herein the authors report a general, safe, and high-yielding strategy to access cyclic diaryl λ³-bromanes. These unique compounds feature reactivity that is appealing and complementary to that of λ³-iodanes, generating arynes under mild reaction conditions and in the presence of a weak base. Accordingly, formal meta-selective transition-metal-free C-O and C-N couplings may be achieved. Mechanistic studies unambiguously support the aryne generation mechanism.
