摘要:

报道了一种用于端炔水合反应的水溶性salen-Co(Ⅲ)配合物催化剂,在使用硫酸作为共催化剂的条件下能高效得到产物甲基酮. 该催化剂用量少,反应结束后可利用简单的萃取实现产物与催化剂分离,简化了后处理过程. 此外,催化剂还可回收重复使用,但催化剂活性会略有下降.

Abstract:

A water-soluble salen-Co(Ⅲ) complex was studied as catalyst for hydration of terminal alkynes to methyl ketones in the presence of H2SO4 as a co-catalyst. The products were obtained with excellent yields using relatively low catalyst loadings and a simple protocol. Notably, the products were easily separated from the catalyst after reaction by extraction, and the catalyst could be recovered and reused with only a slight loss of activity.
