title: Hydroselenation of alkynes by lithium butylselenolate: an approach in the synthesis of vinylic selenides.
abstract: 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.
