Control of chain ends of polyesters in polycondensation of AA and BB monomers by use of solid-phase reagent

For selective synthesis of linear polyester having a functional group at one end, polycondensation between 1,4-butanediol (1a) and sebacoyl chloride (2a) and between 1,12-dodecanediol (1b) and isophthaloyl chloride (2b) was conducted in the presence of ox

Copper-Catalyzed Trifluoromethylthio-arylsulfonylation of Styrene Derivatives via the Insertion of Sulfur Dioxide

A copper-catalyzed four-component trifluoromethylthio-arylsulfonylation between styrene derivatives, AgSCF3, aryldiazonium tetrafluoroborates, and ex situ generated sulfur dioxide (from SOgen) is presented. This reaction features mild reaction conditions, good functional group tolerance, a broad substrate scope, good yields, and excellent diastereoselectivity. Preliminary mechanistic studies revealed that a radical process might be involved in this transformation.

Nickel-Catalyzed Reductive Cross-Coupling of Aryl Bromides with Vinyl Acetate in Dimethyl Isosorbide as a Sustainable Solvent

A nickel-catalyzed reductive cross-coupling has been achieved using (hetero)aryl bromides and vinyl acetate as the coupling partners. This mild, applicable method provides a reliable access to a variety of vinyl arenes, heteroarenes, and benzoheterocycles, which should expand the chemical space of precursors to fine chemicals and polymers. Importantly, a sustainable solvent, dimethyl isosorbide, is used, making this protocol more attractive from the point of view of green chemistry.

Nickel-Catalyzed Ligand-Free Hiyama Coupling of Aryl Bromides and Vinyltrimethoxysilane

We herein disclose the first Ni-catalyzed Hiyama coupling of aryl halides with vinylsilanes. This protocol uses cheap, nontoxic, and stable vinyltrimethoxysilane as the vinyl donor, proceeds under mild and ligand-free conditions, furnishing a diverse variety of styrene derivatives in high yields with excellent functional group compatibility.

Copper-Catalyzed Defluorinative Hydroarylation of Alkenes with Polyfluoroarenes

A catalytic defluorinative hydroarylation of alkenes with polyfluoroarenes in the presence of dppbz-ligated Cu catalyst and silanes was developed. This method provides a straightforward and alternative avenue to synthetic important polyfluorinated arenes with readily available and bench-stable alkenes as latent nucleophiles, and therefore avoids conventional reliance on stoichiometric quantities of organometallic reagents. This reaction proceeds under very mild conditions and exhibits good functional group compatibility and high level of regioselectivity. The synthetic potential of this method was further demonstrated by a gram-scale synthesis, and an array of experimental studies were also carried out to elaborate the probable mechanism.

Disclosed are a polymer, and a mixture or a formulation and an organic electronic device containing same, and applications thereof, and further a monomer of which the polymer is made; the polymer comprises on its side chain a repeating structure unit E, characterizing in that its S1(E)?T1(E))≤0.35 eV or even less, which may allow the said polymer having thermally activated delayed fluorescence (TADF) property. Thus a TADF polymer suitable for printing processes is provided, thereby reducing OLED manufacturing costs.

Process method for preparing [1-(4-vinylphenyl)-1, 2, 2-triphenyl] ethylene

The invention discloses a process method for preparing [1-(4-vinylphenyl)-1, 2, 2-triphenyl] ethylene, comprising the following steps of: 1, styrene used as a raw material reacts with a benzoic acid compound under the action of a catalyst to obtain 4-vinylbenzophenone; and 2, 4-vinyl benzophenone as a raw material reacts with benzophenone under the action of a catalyst so as to obtain [1-(4-vinylphenyl)-1, 2, 2-triphenyl] ethylene. The process method is reasonable in route design, cheap in raw material price and friendly to operators.

Diboron-Assisted Copper-Catalyzed Z-Selective Semihydrogenation of Alkynes Using Ethanol as a Hydrogen Donor

We herein describe a B2Pin2-assisted copper-catalyzed semihydrogenation of alkynes. A variety of alkenes were obtained in good to excellent yields with Z-selectivity under mild reaction conditions. Mechanistic studies indicated that a transfer hydrogenation process was involved and ethanol acted as both a solvent and a hydrogen donor in this reaction. The present protocol enabled convenient synthesis of deuterium-substituted Z-alkenes such as Z-Combretastain A4-d2 in a high deuteration ratio by using readily available ethanol-d1 as the deuterium source.

Pd-Catalyzed Vinylation of Aryl Halides with Inexpensive Organosilicon Reagents Under Mild Conditions

Pd-catalyzed Hiyama vinylation reaction of non-activated aryl chlorides and bromides under mild conditions was developed. The use of efficient vinyl donors and electron-rich sterically hindered phosphine ligands was critical for the success of the reaction. The products of this transformation can be used for Am/Cm separation, an important challenge in nuclear fuel reprocessing. The substituent effect on Am/Cm separating selectivity was also achieved, which could contribute to the development of new chromatographic materials for the separation of Am and Cm.
