Trifluoromethylthiolation of aryl iodides and bromides enabled by a bench-stable and easy-to-recover dinuclear palladium(I) catalyst

Abstract While palladium catalysis is ubiquitous in modern chemical research, the recovery of the active transition-metal complex under routine laboratory applications is frequently challenging. Described herein is the concept of alternative cross-coupling cycles with a more robust (air-, moisture-, and thermally-stable) dinuclear PdI complex, thus avoiding the handling of sensitive Pd0 species or ligands. Highly efficient C-SCF3 coupling of a range of aryl iodides and bromides was achieved, and the recovery of the PdI complex was accomplished via simple open-atmosphere column chromatography. Kinetic and computational data support the feasibility of dinuclear PdI catalysis. A novel SCF3-bridged PdI dimer was isolated, characterized by X-ray crystallography, and verified to be a competent catalytic intermediate. Pd double team: The cross-coupling enabled by an air-, moisture-, and thermally stable dinuclear PdI complex was explored. Highly efficient C-SCF3 coupling of a range of aryl iodides and bromides was achieved and the catalyst was recovered by simple column chromatography, thus highlighting its robustness and the possibility for catalyst recycling. Kinetic and computational data support the feasibility of dinuclear PdI catalysis.

Pinwheel motifs: Formation of unusual homo- and hetero-nuclear aggregates via bridging thiolates

The homohexanuclear complexes [Ni2{Ni(L1)} 4](BF4)4¡¤MeCN, 1, [Pd 2{Pd(L2)}4](BF4)4, 2, and the heteropentanuclear aggregate [Cu2{Ni(L3)} 3](PF6)2, 3, all adopt a ‘pinwheel’ type structural motif via thiolate bridging between square-planar Ni(II) or Pd(II) and between trigonal planar Cu(I) centres, respectively.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 21797-13-7, you can also check out more blogs about21797-13-7

(1-Bromovinyl)-MIDA boronate: A readily accessible and highly versatile building block for small molecule synthesis Dedicated to Professor Paul Wender with deepest admiration on his receipt of the 2012 Tetrahedron Prize for Creativity in Organic Chemistry

Iterative cross-coupling represents a potentially general approach for the simple, efficient, and flexible construction of a wide range of functional small molecules. In this context, (1-bromovinyl)-N-methyliminodiacetic acid (MIDA) boronate is a very useful building block for small molecule synthesis. This compound can serve as a starting material for the preparation of a wide range of 1,1-disubstituted olefin-containing MIDA boronates. This compound can also be used for the iterative cross-coupling-based synthesis of various 1,1-disubstituted olefin-containing targets. Collectively, these results contribute to the expanding generality of the MIDA boronate platform.

Reductive cyclization of halo-ketones to form 3-hydroxy-2-oxindoles via palladium catalyzed hydrogenation: a hydrogen-mediated Grignard addition

Abstract The reductive cyclization of N-oxoacyl ortho-bromoanilides to form 3-hydroxy-2-oxindoles under the conditions of palladium catalyzed hydrogenation is described. This work may be viewed as a prelude to intermolecular hydrogen-mediated Grignard-type reductive couplings of organic halides with carbonyl compounds.

Development and Analysis of a Pd(0)-Catalyzed Enantioselective 1,1-Diarylation of Acrylates Enabled by Chiral Anion Phase Transfer

Enantioselective 1,1-diarylation of terminal alkenes enabled by the combination of Pd catalysis with a chiral anion phase transfer (CAPT) strategy is reported herein. The reaction of substituted benzyl acrylates with aryldiazonium salts and arylboronic acids gave the corresponding 3,3-diarylpropanoates in moderate to good yields with high enantioselectivies (up to 98:2 er). Substituents on the benzyl acrylate and CAPT catalyst significantly affect the enantioselectivity, and multidimensional parametrization identified correlations suggesting structural origins for the high stereocontrol.

Effect of heterocycles on field-effect transistor performances of donor-acceptor-donor type small molecules

Two D?A?D small molecules comprising triphenylamine and diketopyrrolopyrrole were synthesized having either furan or thiophene connected to the fused lactam ring. In this design, furan/thiophene diketopyrrolopyrrole acts as an acceptor and triphenylamine acts as a donor. Propeller shaped triphenylamine has its effect on packing, processability and plays a vital role in determining the pi-pi molecular orbital stacking in such compounds and thus the mobility of charge carriers. With TDPPT and FDPPT, maximum hole carrier mobility obtained is 2.88?¡Á?10?3?cm2?V?1?s?1and 1.60?¡Á?10?3?cm2?V?1?s?1, respectively using bottom gate bottom contact field-effect transistor.
