Herein, CoN, CuN, and NiN complexes with a 14-membered ring hexaazamacrocycle ligand HHAM were synthesised as precursors for ORR and CORR catalysts a one-pot, gram-scale synthesis procedure, which involved microwave heating for only 10 min. Detailed structures of the obtained 14MR-MN complex were revealed by single-crystal X-ray diffraction measurements.

The chemical recycling of polystyrene (PS) waste to value-added aromatic compounds is an attractive but formidable challenge due to the inertness of the C-C bonds in the polymer backbone. Here we develop a light-driven, copper-catalyzed protocol to achieve aerobic oxidation of various alkylarenes or real-life PS waste to benzoic acid and oxidized styrene oligomers. The resulting oligomers can be further transformed under heating conditions, thus achieving benzoic acid in up to 65% total yield through an integrated one-pot two-step procedure.

A convenient and efficient transition-metal-free method has been developed for the C(sp)-H alkoxylation/aryloxylation of 1,4-quinones by direct cross-dehydrogenative coupling with readily available alcohols and phenols in the presence of TEMPO under simple and mild conditions. The method allowed the installation of a wide range of alkoxy/aryloxy groups, exhibited high functional group tolerance, showed a broad substrate scope, afforded good to excellent yields of products in a simple one-pot operation, and could be performed on a gram scale. Mechanistic investigation indicated the involvement of the radical pathway.

A streamlined strategy for the one-pot synthesis of isoxazolone analogues has been developed through an acceptorless dehydrogenative annulation (ADA) pathway by employing new Ru(II) hydride complexes as effective catalysts. New Ru(II) complexes () tailored with N̂O chelating carbazolone benzhydrazone ligands were synthesized and their formation was confirmed using analytical and spectral techniques including FT-IR and NMR. The structural configuration of the complexes featuring an octahedral geometry around the Ru(II) ion was precisely determined by single-crystal X-ray diffraction analysis.

High-performance, environmentally friendly indium phosphide (InP)-based quantum dots (QDs) are urgently needed to meet the demands of rapidly evolving display and lighting technologies. By adopting the highly efficient and cost-effective one-pot method and utilizing aluminum isopropoxide (AIP) as the Al source, a series of Al-doped InP/(Al)ZnS QDs with emission maxima ranging from 480 to 627 nm were synthesized. The photoluminescence quantum yield (PLQY) of the blue, green, yellow, orange, and red QDs, with emission peaks at 480, 509, 560, 600, and 627 nm, reached 34%, 62%, 86%, 96%, and 85%, respectively.

Transition-metal-regulated radical cross coupling enables the selective bonding of two distinct transient radicals, whereas the catalytic method for sorting two almost identical transient radicals, especially similar benzyl radicals, is still rare. Herein, we show that leveraging dual photoredox/cobalt catalysis can selectively couple two similar benzyl radicals. Using easily accessible methylarenes and phenylacetates (benzyl N-hydroxyphthalimide (NHPI) esters) as benzyl radical sources, a range of unsymmetrical 1,2-diarylethane classes via the 1°-1°, 1°-2°, 1°-3°, 2°-2°, 2°-3° and 3°-3° couplings were obtained with broad functional group tolerance.
