Abstract
The reaction of various cyclic and acyclic alkynes with lithium dust ( 2% sodium) to form vicinal dilithioalkenes has been investigated: Alip hatic alkynes, e.g. 5-hexyne (27a), exclusively afford the correspondi ng (E)-dilithioalkenes, insoluble solids which ave stable at room temp erature and allow access to a variety of tetrasubstituted olefins in a cceptable yields.
