چکیده

Dioxygen activation at copper(i) centres is of primary importance for the development of sustainable oxidation catalysis, but regeneration of copper(i) centres after each catalytic cycle remains a major problem for multi-turn-over catalysis. This work demonstrates that an artificial reductase, made of flavin cofactors incorporated into a water soluble polymer, efficiently reduces a Cu(ii)TPA complex in the presence of NADH in water.

Green and efficient synthesis of propargylamines via A3 coupling reaction using a copper (II)–thioamide combination

A one pot green three‐component coupling reaction of aldehyde, phenylacetylene, and amine derivatives in the presence of copper (II)–thioamide combination as a novel and efficient heterogeneous catalyst under solvent–free conditions is reported. The catalyst displayed high activity and afforded the corresponding propargylamines in good to high yields. The key to this procedure was the generatio...

Lithium, sodium and potassium picolyl complexes: syntheses, structures and bonding.

Synthetically important for introducing a picolyl scaffold into a molecular construction, alkali metallated picoline (methylpyridine) complexes are also interesting in their own right for the diversity of their ligand-metal bonding possibilities. Here the syntheses of seven new such complexes are reported: namely three 4-picoline derivatives 4-picLi·Me6TREN, 1, 4-picNa·Me6TREN, 2, and [4-picK·2...
