摘要

In the presence of p-toluenesulfonic acid, the reaction of alkenes with diselenides and oxidant m-chloroperbenzoic acid proceeds efficiently in alcohols at room temperature, and was developed into a convenient procedure for the alkoxylselenenylation of alkenes, forming a series of corresponding 2-alkoxy-1-selenenyl compounds with high regioselectivity and good yields. The reaction conditions are optimized and a plausible mechanism for the acid promotion is suggested.
