organic molecule is reported. Various aspects of the reaction of SeCl2 with propargyl alcohols, i.e., identity of reacting functionality, regiospecificity, and stereospecificity, differ from expectations based on known reactions of these alcohols with SCl2. Selenium dihalides undergo smooth 1,2‐addition to the triple bond of various propargylic alcohols resulting in the formation of the corresponding functionalized
