Summary: The use of water as a reaction solvent is ideal for green chemistry, but carrying out catalytic reactions with transition metal catalysts in aqueous media is challenging. To enhance the scope of allylation reactions in water, a series of Pd diphosphine complexes co-immobilized with organic groups onto mesoporous silica supports was synthesized. The newly synthesized catalyst demonstrated improved catalytic allylation performance in water, expanding the toolkit of transition-metal-catalyzed reactions in aqueous media. The results have far-reaching consequences in academia and industry due to the wide use and scope of allylation reaction.

Summary: In this study, a low-metal iron-supported catalyst (Fe20/NC-Mg) was reported for the efficient synthesis of quinoxaline compounds, using water as a solvent and without additional bases. The synergistic effect of FeNx site and Mg (OH)2 nanorods in the catalyst played a key role in achieving high yields (82-91%) in 16 examples. The gram-level synthesis and reusability of the catalysts after four cycles demonstrated its industrial application potential.
