The versatility of organic ligand and metal coordination geometry produced polymer with intriguing network structure exciting functional properties. Herein, we have synthesized a copper (Cu-HS) using an amino acid based multidentate explored its electrocatalytic OER activity in alkaline condition. Single crystal structural studies showed the formation 1D inclusion lattice water. Copper ions Cu-HS displayed octahedral square pyramidal geometry. Electrocatalytic medium strongly enhanced for that required overpotential 273 mV to achieve benchmark current density 10 mA/cm2. Tafel slope analysis electrochemical impedance suggested faster reaction kinetics at electrode surface modified Cu-HS. After catalysis, XPS FTIR spectra conversion oxide during electrocatalysis.

A novel catalytic system for homocoupling terminal acetylenes was elaborated based on CuCl as a catalyst (10 mol%), TMEDA base and CCl4 an oxidant. The influence of the solvent, base, amount reaction investigated. Methanol found to be solvent choice. broad synthetic scope demonstrated. Diynes with various substituents were prepared in up 92% yields. possible mechanism is discussed.

Abstract Two oxidovanadium(IV) complexes [VO(xbp‐sc)] ( 1 ) and [VO(xbp‐tc)] 2 were prepared using hydrazine‐ether mixed functionality ligands Hxbp‐sc I Hxbp‐tc II ), respectively. Complexes carefully grafted separately into imidazole‐modified chloromethylated polystyrene (Ps−Im) unmodified (PS−Cl) beads. Successfully anchored vanadium Ps−Im‐[VO(xbp‐sc)] 3 Ps−Im‐[VO(xbp‐tc)] 4 Ps‐[VO(xbp‐sc)] 5 Ps‐[VO(xbp‐tc)] 6 tested for their catalytic potential towards the oxidation of aliphatic alcohols in presence hydrogen peroxide. Polymer‐grafted catalysts display excellent substrate conversion compared to most recent reports good recyclability up three cycles without losing much reactivity. High TOF values range 183–591 h −1 are observed supported – . The highest is ethanol (63–97 %) under optimized reaction conditions. Mainly, better obtained with polymer beads than those on ). Moreover, semicarbazide group ligand framework show reactivity alcohol fewer carbon atoms. On contrary, longer chains oxidize more easily catalyst thiosemicarbazide frameworks
