中文摘要：
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。
英文摘要：
A water-soluble salen-Co（Ⅲ） complex was studied as catalyst for hydration of terminal alkynes to methyl ketones in the presence of H2S04 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.
