regardless of the solvent composition. Vinyl bromide 1 reacts slowly with n-BuLi at room temperature in a variety of ether and heptane-ether mixtures to afford a mixture of products including significant quantities of recovered starting material. The results of these experiments demonstrate that lithium−bromine exchange between a vinyl bromide and either t-BuLi or n-BuLi at temperatures significantly above
