The Pd-catalyzed carbene coupling reaction of -tosylhydrazones and benzyl bromides has been developed into a polymerization process for the first time, providing an efficient method for the synthesis of poly(arylene vinylene)s (PAVs). This method affords PAVs bearing -vinylene units predominantly. It can also introduce a CF group on each vinylene carbon atom in the polymer main chain. The polymerization has a broad scope and the resultant polymers exhibit interesting optical properties and good thermal stabilities.

Due to the diverse chemical and physical properties of functional groups, mild and controllable ligation methods are often required to construct complex drugs and functional materials. To make diverse sets of products with tunable physicochemical properties, it is also useful to employ complimentary ligation methods that adopt the same starting materials. Here, we disclose the efficient and modular synthesis of amides or thioamides through the chemical ligation of acyl silanes with amines, simply by turning a light on or off.

Boron compounds are widely employed in organic chemistry, pharmaceuticals, and materials science. Among them, borylated heterocycles serve as versatile synthons for the construction of new C-C or C-heteroatom bonds via coupling or radical processes. Such methods for direct C-H borylation reactions are of high synthetic value to reduce the number of synthetic steps and the amount of waste and to improve efficiency.

Silver drugs have played a vital role in human healthcare for the treatment of infections for many centuries. Currently, due to antibiotic resistance, a potential scenario or the application of silver complexes may arise as substitutes for conventional antibiotics. In this perspective, N-heterocyclic carbene (NHC) ligands have been selected as carrier molecules for silver ions.

Carbene-metal-amide (CMA) complexes have diverse applications in luminescence, imaging and sensing. In this study, we designed and synthesized a series of CMA complexes, which were subsequently doped into a PMMA host. These materials demonstrate light-induced dynamic phosphorescence, attributed to their long intrinsic triplet state lifetime (τP,int, in the μs-ms scale), high intersystem crossing (ISC) rate constant (kISC, up to 107 s-1), and bright phosphorescence.

Planar hexacoordination is an extremely uncommon phenomenon for the atoms that belong to the main group. Within this article, we have analyzed the potential energy surfaces (PES) of ABeCB (A = N, P, As, Sb, and Bi) clusters in neutral, monocationic, monoanionic, dicationic, and dianionic states using density functional theory (DFT). Among which PBeCB, PBeCB, AsBeCB, AsBeCB, SbBeCB, and BiBeCB clusters contain a planar hexacoordinate boron (phB) atom in the global minimum energy structures with symmetry.
