Summary: An intensive study on organotin cations with weakly coordinating trifluoromethanesulfonate/arylsulfonate has provided crucial insights into their stability, structural aspects, and catalytic role. The chemistry involving alkanesulfonate ligands remains incomplete due to the presence of strong Sn-O bond. In this study, the scope of diorganostannates, [n-Bu4N][R2Sn(OSO2R1)3] (R = n-Bu, R1 = Me(1), Et(2); R = Ph, R1 = Me(3)), as reactive substrates in the presence of adventitious water was investigated, leading to the formation of [n-Bu2SnOH(OSO2Me)] (4), [n-Bu2Sn(H2O)4][n-Bu4N][OSO2Et]3 center dot H2O (5), and [Ph2Sn(H2O)4][n-Bu4N]2[OSO2Me]4 (6). The crystallographic studies of these compounds reveal their structural identity and the role of alkanesulfonate anions in the formation of supramolecular assemblies.

Summary: Analogous to alkoxide ligands, metal boroxide and boryloxy complexes are a lesser studied type of hard anionic O- ligands. A new series of amine-stabilized Li, Sn(II), and Zn boryloxy complexes with electron-rich tetrahedral boron centers were synthesized and characterized. The complexes were characterized using 1D, 2D, and DOSY NMR, and solid-state structures were determined via single-crystal X-ray diffraction. The amine-stabilized boryloxy ligand showed enhanced x-donor ability due to electron donation from the amine functionality into the p-orbital of the boron atom, as evidenced by computational quantum chemical studies.

Summary: Introducing sulfur atoms into polymer backbones can utilize abundant chemical industry by-products and adjust polymerization thermodynamics for polymer recycling. By replacing oxygen with sulfur atoms in bio-derived polymers, their properties can be fine-tuned and application scope widened. This study reports the synthesis and characterization of cyclic carbonate and thiocarbonate monomers made from carbohydrate derivative d-glucal, varying the number and position of sulfur atoms in the polymerizable ring. The influence of sulfur on polymer properties such as ring strain, monomer conversion, crystallinity, thermal degradation, and glass transition temperature is examined, providing insights for the design of sulfur-containing renewable polymeric materials in the future.

Summary: We report the catalytic hydroboration of esters and nitriles using a single titanium(IV) metal complex as a sustainable, economical, and efficient pre-catalyst. The complex showed excellent activity towards the hydroboration of a wide array of esters and nitriles with pinacolborane, giving high yields of alkoxyboranes and diboryl amines. In addition, the complex demonstrated greater tolerance to various functional groups. A plausible mechanism involving the formation of a titanium-hydride species as an active catalyst was proposed based on kinetics and NMR studies.

Summary: In this study, d-xylose 3,5-anyhydrosugar (d-Ox) was used in the ring-opening copolymerisation (ROCOP) with isothiocyanates to form alternating AB-type copolymers with imidothiocarbonate linkages. The use of an Al(iii)-based aminotrisphenolate complex as catalyst allowed the synthesis of thermally robust polymers with high glass-transition temperatures. The reactivity can be tailored by using an Al(iii) porphyrin complex as catalyst, enabling the formation of a non-polymerisable cyclic thionocarbamate byproduct. The polymers exhibited degradation under acidic and basic conditions, as well as photodegradation.

Summary: Two Schiff base complexes, [CuL2] (Cu-Sal) and [CoL3] (Co-Sal), were synthesized and characterized. Crystal structure analysis showed a square planar geometry around Cu(ii) and various intermolecular non-covalent interactions in Cu-Sal. Both complexes were used as sensitizers in TiO2 based dye sensitized solar cells (DSSCs), and Co-Sal exhibited better photovoltaic performance than Cu-Sal due to improved light absorption and dye loading.
