1,3,5-Tris(functionalised-phenylethynyl)benzene-metal complexes: Synthetic survey of mesoporous coordination polymers and investigation of their carbonisation

10.1039/b715550f

The research focuses on the synthesis and investigation of 1,3,5-tris(functionalised-phenylethynyl)benzene-metal complexes, with the aim of creating mesoporous coordination polymers and exploring their carbonisation to produce porous carbon materials. The study successfully synthesized a series of multicoordinate 1,3,5-tris(functionalised-phenylethynyl)benzenes (1–9) and constructed coordination polymers using these organic linkers and copper ions. The carbonisation of these linkers resulted in microporous carbons, and the coordination polymer 7e, prepared from the reaction of 1,3,5-tris(4-carboxyphenylethynyl)benzene tripotassium salt (K37) and copper(II) nitrate, was identified as a microporous material.

Mechanism of Formation of Schiff Base Complexes. Part 3. Kinetic Template Effect of Copper(II) in the Condensation Reaction of the Salicylaldehydato-ion with a Polyfunctional Diprimary Amine

10.1039/DT9820001825

The research investigates the kinetic template effect of copper(II) ions in the condensation reaction of salicylaldehydato-ion (sal) with diethylenetriamine (dien). The study aims to understand how copper(II) ions influence the reaction mechanism and kinetics, particularly in promoting first-order reactions within its coordination sphere. The key chemicals used include salicylaldehydato-ion, diethylenetriamine, copper(II) nitrate, and various solvents such as methanol and 1,2-dichloroethane. The researchers found that in the presence of copper(II), the reaction proceeds through a first-order kinetic process, forming a labile ternary complex where interligand condensation occurs. The study concludes that while copper(II) ions can reduce the reaction order, the activation energy for the template reaction is higher compared to the bimolecular condensation, indicating that the coordination of functional groups to the metal perturbs the optimal reaction geometry. This perturbation results in a less favorable entropy of activation for the template reaction, highlighting the limitations of metal ions in mimicking the efficiency of enzyme-catalyzed reactions.

Bringing an old biological buffer to coordination chemistry: New 1D and 3D coordination polymers with [Cu₄(Hbes)₄] cores for mild hydrocarboxylation of alkanes

10.1021/ic1007999

The study explores the use of the biological buffer H3bes, N,N-bis(2-hydroxyethyl)-2-aminoethanesulfonic acid, in synthetic coordination chemistry to create new water-soluble 1D and 3D CuII/Na coordination polymers 1-3 with [Cu4(Hbes)4] cores. These polymers are generated through aqueous-medium self-assembly using copper(II) nitrate as the metal source, H3bes as the main ligand, benzoic acid derivatives as auxiliary ligands, and sodium hydroxide to regulate pH. The polymers' structures feature tetracopper(II) cores that promote mild hydrocarboxylation of gaseous alkanes like propane and butane to carboxylic acids in the presence of CO and H2O, achieving yields up to 95%. This research not only introduces H3bes as a novel ligand in coordination chemistry but also demonstrates the potential of these water-soluble copper complexes for the oxidative functionalization of inert alkanes under mild conditions.
