In heterogeneous catalysis, the catalyst is in a different phase from the reactants. SDS of cas: 538-58-9, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 538-58-9, name is 1,5-Diphenylpenta-1,4-dien-3-one. In an article£¬Which mentioned a new discovery about 538-58-9
Zirconium borohydride piperazine complex, an efficient, air and thermally stable reducing agent
A zirconium borohydride piperazine complex (Ppyz)Zr(BH4) 2Cl2, obtained by the reaction of an ethereal solution of ZrCl4 and LiBH4 with piperazine is a stable, selective and efficient reducing agent. (Ppyz)Zr(BH4)2Cl 2 reduces aldehydes, ketones, silylethers, alpha, beta-unsaturated carbonyl compounds and esters. The reactions were performed in diethyl ether at room temperature or under reflux, and the yields of the corresponding alcohols were excellent. The selective reduction of aldehydes in the presence of ketones and complete regioselectivity in the reduction of alpha,beta-unsaturated carbonyl groups were observed.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 538-58-9, help many people in the next few years.SDS of cas: 538-58-9
