In contrast to previous strategies, our method uses gem-dihaloalkanes as non-stabilized carbene precursors and operates through a radical reaction pathway. Mechanistic investigations, encompassing deuterium-labelling experiments, crossover experiments, kinetic isotope effect studies, and control experiments, ...
It is also reduced by the HCl gas pretreatment to the catalyst before the benzylation reaction. The Ga 2O 3/H-ZSM-5 and In 2O 3/H-ZSM-5 catalysts showed excellent reusability in the benzene benzylation. Kinetics of the benzene benzylation (using an excess of benzene) over the H-Ga...
each step, several primary factors that significantly affect the removal efficiency in the advanced oxidation system (AOPs) were examined. These variables consist of pH, photocatalyst dosage, lead concentration, and reaction temperature. The synthetic photocatalyst showed optimal performance in the removal ...
KOH was used as the solvent for the reaction to promote the formation of bimetallic single-atom catalysts. After cooling to room temperature, the precipitate was collected by centrifugation, and washed with 3 M HCl and water. Then, the precipitate in black was dried under vacuum, to give ...
