正丁基锂与单质硒反应生成丁基硒化锂，再与炔进行硒氢化反应，以高产率合成了乙烯基硒醚。硒氢化的区域和立体化学取决于与炔键合的取代基的性质。
Vinylic selenides were prepared in good yields by hydroselenation of alkynes with lithium butylselenolate generated by reaction of n-butyllithium with elemental selenium. The regio- and stereochemistry of the hydroselenation depend on the nature of the substituents bonded to the alkyne.
