Methods for the direct synthesis of difluoromethylated arenes are sparse, despite the importance of the difluoromethyl group in medical, agro-, and materials chemistry. A palladium-catalyzed decarbonylative cross-coupling reaction of acid chlorides with a difluoromethyl zinc reagent is achieved to access difluoromethylated compounds. The transformation proceeds at room temperature and shows broad functional group tolerance, thus providing a general and efficient method for decarbonylative difluoromethylation of a wide range of aromatic carboxylic acids.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 32005-36-0

Ruthenium-catalyzed CH silylation of methylboronic acid was achieved by use of 2-(1H-pyrazol-3-yl)aniline as a removable alpha-directing modifier on the boron atom. Crosscoupling of the product, i.e., (phenyldimethylsilyl) methylpinacolborane, with aryl halides proceeded in the presence of a [PdCl 2(dppf)] catalyst and CsOH as a base.

Carbonic anhydrase (CA) has been widely used in gas separation membranes because of its high affinity for CO2 molecules. In this work, a novel biomimetic material (Co-2,6-bis(2-benzimidazolyl)pyridine, CoBBP) which has a similar molecular structure to the CA enzyme but with higher stability and a lower price was successfully synthesized. The excellent thermal stability, dispersibility and high CO2 selectivity make CoBBP a promising alternative to CA. Then, a series of Pebax-CoBBP mixed matrix membranes were constructed to explore their capability for CO2/N2 separation. Compared to the pristine Pebax-1657, the Pebax-CoBBP mixed matrix membrane with the optimized 1.33 wt% CoBBP loading showed an improved CO2 permeability of 675.5 barrer and a CO2/N2 selectivity of 62, surpassing the Robeson upper bound (2008). Furthermore, the hydrogen bonds between CoBBP and polyamide chains improved the chain stiffness of the linear glassy polymer, ensuring good operational mechanical stability. In short, this work could provide a promising method to exploit alternatives to the CA enzyme and to fabricate biomimetic membranes.

Efficient and rapid access to nanographenes and pi-extended fused heteroaromatics is important in materials science. Herein, we report a palladium-catalyzed efficient one-step annulative pi-extension (APEX) reaction of polycyclic aromatic hydrocarbons (PAHs) and heteroaromatics, producing various pi-extended aromatics. In the presence of a cationic Pd complex, triflic acid, silver pivalate, and diiodobiaryls, diverse unfunctionalized PAHs and heteroaromatics were directly transformed into larger PAHs, nanographenes, and pi-extended fused heteroaromatics in a single step. In the reactions that afford [5]helicene substructures, simultaneous dehydrogenative ring closures occur at the fjord regions to form unprecedented larger nanographenes. This successive APEX reaction is notable as it stiches five aryl?aryl bonds by C?H functionalization in a single operation. Moreover, the unique molecular structures, crystal-packing structures, photophysical properties, and frontier molecular orbitals of the thus-formed nanographenes were elucidated.

This paper describes the haloboration reaction of 1-alkynes and its application to organic synthesis. B-Bromo- or B-iodo-9-borabicyclo left bracket 3. 3. 1 right bracket -nonane (B-X-9-BBN) and other haloboranes react readily with 1-alkynes through Markovnikov cis-addition of the X-B moiety to C EQUVLNT C bonds. The haloboration occurs chemoselectively at terminal C EQUVLNT C bonds, but not at internal C EQUVLNT C, terminal and internal C equals C bonds. The haloboration adducts (I) thus obtained are valuable intermediates to afford various organic compounds stereospecifically in good yields, some of which are shown.

Polythiophenes (PTs) featuring di(ethylene glycol)-substituted 2,5-thienyl diketopyrrolopyrrole (DG-TDPP) moieties as conjugated units in the polymer backbone and tert-butyl-substituted triphenylamine (tTPA)-containing moieties as pendant units have been synthesized through Stille coupling. Incorporating the electron-deficient DG-TDPP moieties within the polymer backbone and appending the tTPA units promoted charge balance and efficient conjugation within the extended conjugated frameworks of the polymers, resulting in lower band gap energies and red-shifting the maximum UV-Vis absorption wavelength. The influence of the DG-TDPP content on the optical, electrochemical, and photovoltaic (PV) properties of the polymers has been studied. Incorporating a suitable content of DG-TDPP moieties in the polymer backbone enhanced the solar absorption ability and conjugation length of the PTs. The PV properties of bulk-heterojunction solar cells based on PT/fullerene derivatives improved after incorporating DG-TDPP units in the backbones of the side chain-conjugated PTs.

The coordination chemistry of the ligand bis[2-(3,5-dimethyl-1-pyrazolyl) ethyl]ether (L1) was tested in front of Pd(II) and Pt(II). Complexes cis-[MCl2(L1)] (M=Pd(II) and Pt(II)) were obtained, due to the chelate condition of the ligand and the formation of a stable 10-membered ring. The crystal structure of cis-[PtCl2(L1)] was resolved by X-ray diffraction. Treatment of [PdCl2(L 1)] or [Pd(CH3CN)4](BF4) 2 with AgBF4 in the presence of L1 gave the complex [Pd(L1)2](BF4)2. The initial cis-[PdCl2(L1)] was recovered by reacting [Pd(L1)2](BF4)2 with an excess of NEt4Cl. Reaction of [Pt(CH3CN)4](BF 4)2 (generated in situ from [PtCl2(CH 3CN)2] and AgBF4 in acetonitrile) with ligand L1 yields complex [Pt(L1)2](BF 4)2.

The first Pd-catalyzed Mizoroki-Heck-type reaction of [Ph2SRfn][OTf] with alkenes is described. The reaction of [Ph2SRfn][OTf] (Rfn = CF3, CH2CF3) with alkenes in the presence of 10 mol% Pd[P(t-Bu)3]2 and TsOH at room temperature provided the corresponding phenylation products in good to high yields. The bases that benefit the traditional Mizoroki-Heck reactions severely inhibited the transformation with [Ph2SRfn][OTf], whereas acids significantly improved the reaction. This protocol supplies a new class of cross-coupling partners for Mizoroki-Heck-type reactions and gains important insights into the reactivity of phenylsulfonium salts either with or without fluorine-containing alkyl groups as the promising phenylation reagents in organic synthesis.
