Summary: The facile synthesis of the first bis-N-heterocyclic imine-stabilized chlorosilyliumylidene and its consecutive reaction with PPh3AuCl and K2Fe(CO)(4) resulted in the formation of a unique heterobimetallic complex. The complex bears an unusual linear Si-Au-Fe structure with a rare anagostic interaction between the gold atom and a CH bond. Computational analysis shows strong hyperconjugative back donation from the gold(I) atom to the silyliumylidene ligand.

Summary: Two rare earth coordination polymers were synthesized using zwitterionic ligands. The structural characterization revealed differences in the coordination environments of La3+ ions in 1 and Gd3+ ions in 2. Both polymers exhibited good thermostability, decomposing at high temperatures to form La2O3 and Gd2O3. Magnetic properties of 2 were studied in the temperature range of 2-300 K.

Summary: We review the known chemistry of the cyaphide ion, (C=P)(-), including its isolation and characterization after almost a hundred years of study. Recent developments have shown the viability of cyaphide transfer in established salt-metathesis protocols, and its physical properties have been explored in comparison to its lighter congener cyanide. Studies suggest that the cyaphide ion has potential as a versatile chemical reagent for the synthesis of novel molecules and materials, opening up interesting avenues for future investigation.

Summary: In this study, imidazo[1,5-a]pyridine heterocycles were successfully synthesized via Cu(II)-mediated functionalization of alpha '-C(sp(3))-H bonds of pyridinylaldimines and subsequent cyclization. The strategy utilized the directing ability of heteroleptic aldimine and pyridine groups in the substrate to selectively functionalize alpha '-methylene groups over distant methyl or methylene groups. The observed correlation between the nature of anionic ligands bonded to copper and the chemoselectivity of the C(sp(3))-H activation process suggests a concerted metalation-deprotonation pathway prior to cyclization.

Summary: The metal-free catalytic hydrogenolysis of silyl triflates and halides to hydrosilanes is achieved using arylborane Lewis acids as catalysts. The catalyst acts as a Frustrated Lewis Pair and is able to split H-2 and generate a boron hydride intermediate capable of reducing (pseudo)halosilanes. This metal-free organocatalytic system competes with metal-based catalysts and enables the formation of a variety of hydrosilanes at room temperature in high yields under low hydrogen pressure.

Summary: In order to reduce our reliance on fossil feedstock, alternative sources for polymeric materials have been sought in recent years. This study presents a new approach to the formation of a useful monomer for polyesters, succinic anhydride, through the catalytic carbonylation of bio-sourced acrylic acid. The use of an Earth-abundant metal catalyst, [Co-2(CO)(8)], along with a bidentate ligand, 1,2-bis(dicyclohexylphosphino)ethane (dcpe), and H-2, successfully tackles the challenging carbonylation of unsaturated carboxylic acids.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
