Therefore, when using water as the reaction medium, the excellent wettability could effectively accelerate the contact between catalyst and reactants, resulting in a better performance. Early in 2005, Prado and co-workers attached Nb2O5 on CA and enhanced its contact with water rather than ...
3A).38 In the reaction of HCHO with (H2O)2, a double proton transfer process is observed. The additional water acts as a homogeneous catalyst to promote proton transfer from H2O to HCHO. The potential energy barrier is reduced to 23.1 kcal/mol (Fig. 3B).38 Even though the activation ...
Chlorinated phenol tends to deprotonate at its hydroxyl group in water, and the ionized CPs dominate the species of reactants in electrocatalytic hydrodechlorination reaction (EHDC). Here we determined the high tendency of the hydroxyl group deprotonation on 2,4-dichlorophenol (2,4-DCP) was hig...

First, reaction of zinc oxide with a fatty acid produces soluble zinc ion; second, zinc becomes securely bound to one or two silanols. Zinc attachment displaces part of the free water and creates a heterogeneous surface in which the ratio of zinc-to-water is variable. This ratio will ...
Catalyzed cross-coupling of alkenyldiisobutylaluminums with alkenylhalidesand aryl iodides and bromides has been developed. The procedure is to make the (E)-1-alkenyldiisobutylaluminum component by reaction of Bui2AlH with a 1-alkyne. This is then allowed to react with a (Z)- or (E)-1-halo...
