Two benzyne-enabled desulfurization reactions have been demonstrated which convert diaryl sulfoxides and heteroaryl sulfoxides to biaryls and desulfurized heteroarenes, respectively. The reaction accessing biaryls tolerates a variety of functional groups, such as halides, pseudohalides, and carbonyls. Mechanistic studies reveal that both reactions proceed via a common assembly process but divergent disassemblies of the generated tetraaryl(heteroaryl) sulfuranes.

A side-chain-extended conjugation strategy is demonstrated here to improve the photocatalytic performance of a linear conjugated polymer for hydrogen production from water. For this, polymers P0, P1, and P2 were designed and synthesized based on benzodithiophene and dibenzothiophene S,S-dioxide. Compared with P0, P1 and P2 have two additional thiophene units conjugated in the polymer skeleton along the main-chain and side-chain directions, respectively. Studies found that side chain-conjugated functionalization in P2 enhances thermal stability, redshifts light-absorption bands, narrows the polymer bandgap, prolongs the exciton lifetime, enlarges the photocatalytic over-potential, increases charge mobility, reduces charge transport resistance, and thus improves the hydrogen evolution rate (HER) by a factor of 160 fold. Although performance improvement is still observed in P1, the factor is only 3.6 fold. Thus, P2 exhibits the most promising performance among the three polymers with a HER of 20 314 mu mol g(-1) h(-1) in the presence of 3 wt% Pt cocatalyst and a record apparent quantum yield of 7.04% at 500 nm, rendering it an excellent green light photocatalyst.

Next-generation membranes use highly engineered polymeric structures with enhanced chain rigidity, yet difficulties in polymerization often limit molecular weights required for film formation. Addition-type polynorbornenes are promising materials for industrial gas separations, but suffer from these limitations owing to endo-exo monomeric mixtures that restrict polymerization sites. In this work, a synthetic approach employing the reductive Mizoroki-Heck reaction resulted in exo-selective products that polymerized up to >99% yields for ROMP and addition-type polymers, achieving molecular weights an order of magnitude higher than addition-type polymers from endo-exo mixtures and impressive side group stereoregularity. Due to this increased macromolecular control, these polynorbornenes demonstrate unique solubility-selective permeation with mixed gas selectivities that exceed commercially used PDMS. In addition to thermal and structural characterization, XRD and computational studies confirmed the results of pure and mixed-gas transport testing, which show highly rigid membranes with favorably disrupted chain packing.

Five novel triphenylamine derivatives with two silyl ether protecting groups were readily synthesized and further underwent silyl polycondensation to obtain novel electro-active aromatic polyethers. These polymers exhibited high optical transparency, were colourless, were soluble in many organic solvents, and had useful levels of thermal stability associated with moderately high glass-transition temperatures and char yields. These anodically polymeric electrochromic materials displayed highly reversible electrochemical and electrochromic behaviour, with interesting and useful multi-colour changes related to their different oxidation stages.

While there is a growing interest in harnessing synergistic effects of more than one metal in catalysis, relatively little is known beyond bimetallic systems. This report describes the straightforward access to an air-stable Pd trimer and presents unambiguous reactivity data of its privileged capability to differentiate C-I over C-Br bonds in C-C bond formations (arylation and alkylation) of polyhalogenated arenes, which typical Pd-0 and Pd-I-Pd-I catalysts fail to deliver. Experimental and computational reactivity data, including the first location of a transition state for bond activation by the trimer, are presented, supporting direct trimer reactivity to be feasible.

Quality Control of 4,4′-Dibromobiphenyl. I found the field of Chemistry; Engineering very interesting.

A pre-formed catalyst Pd2+/PANI composite for C-C coupling reaction was synthesized by combining the self-stabilized dispersion polymerization method with the in-situ composite material. Experiments have confirmed that the relatively high reduced structure (75%) in the polyaniline carrier is more favorable for the coupling reaction. Raman spectroscopy, solid nuclear magnetic, and X-ray photoelectron spectroscopy were performed to characterize the structures. The pre-formed catalyst has uniform coordination of divalent palladium and nitrogen in different valence states of the carrier polyaniline, which shows a good synergistic effect in the catalytic Ullmann reaction, and greatly reduces the use of reducing agents such as hydrazine hydrate. Compared with other studies, we analyzed the catalytic reaction mechanism in detail through real-time online infrared and XPS characterization. The results show that the divalent palladium in the catalyst and the zero-valent palladium generated by the in-situ reaction synergistically promote the reaction, while the polyaniline support acts as a stabilizer and dispersant, which prevents the agglomeration of the metal particles and prolongs increased catalyst life. The prepared Pd2+/PANI composites will become the most attractive alternative to traditional organic materials due to their wide applicability, high catalytic activity, stable recycling and relatively low price. This work provides a new theoretical basis for the understanding of the essential driving force of PANI catalytic activity and the cognition of the micro mechanism of action. (C) 2020 Elsevier Inc.

Porous metal-organic frameworks (MOFs) have excellent characteristics for the adsorptive removal of environmental pollutants. Herein, we introduce a new series of highly stable MOFs constructed using Fe3+ and Al3+ metal ions and bisphosphinate linkers. The isoreticular design leads to ICR-2, ICR-6, and ICR-7 MOFs with a honeycomb arrangement of linear pores, surface areas up to 1360 m(2) g(-1), and high solvothermal stabilities. In most cases, their sorption capacity is retained even after 24 h of reflux in water. The choice of the linkers allows for fine-tuning of the pore sizes and the chemical nature of the pores. This feature can be utilized for the optimization of host-guest interactions between molecules and the pore walls. Water pollution by various endocrine disrupting chemicals has been considered a global threat to public health. In this work, we prove that the chemical stability and hydrophobic nature of the synthesized series of MOFs result in the remarkable sorption properties of these materials for endocrine disruptor bisphenol A.

A nickel-catalyzed cross-electrophile coupling reaction between (hetero)aryl bromides and 2,2-difluorovinyl tosylate is presented. This protocol provides facile incorporation of the gem-difluorovinyl moiety in organic molecules. The method features mild reaction conditions, good functional group tolerance, and excellent yields. Furthermore, mechanistic experiments and DFT studies indicate a Ni(0)/Ni(II) catalytic cycle, thus differing from the currently accepted catalytic cycle for nickel-catalyzed C(sp(2))-C(sp(2)) cross-electrophile coupling reactions.

Radical cations of bis(dianisylamino)-terminated oligo(p-phenylene)s (OPPs) with up to five phenyl moieties were characterized by means of UV/Vis-NIR and variable-temperature ESR spectroscopy to investigate the bridge-length-dependence on intramolecular charge/spin self-exchange between two nitrogen redox-active centers. Additionally, a comparative study between bis(dianisylamine)-based mixed-valence (MV) radical cations connected by p-terphenylene and hexa-peri-hexabenzocoronene (HBC) pi-bridging units also provided information on the influence of extended pi-conjugation over the OPP-bridge due to the planarization between adjacent phenylene units on the strength of electronic coupling. The present study on a homologous series of organic MV systems clarifies the attenuation factor through the OPP-bridge and the linear relationship between the electrochemical potential splitting and the electronic coupling in the region of intermediate-to-weak electronic coupling regime.
