2-Alkynes are metallated almost exclusively at the terminal position by t-BuLi in ether, in the presence of TMEDA. Subsequent reaction. e.g. with TMS chloride gives propargylic silanes: Synthesis, 111 (1984). Attempted lithiation with n-BuLi in THF, followed by alkylation, was found to give poor results. However, lithiation at -78o in the presence of HgCl2, allowed the monobenzylated product, 1,4-diphenyl-1-butyne, to be obtained in good yield: J. Org. Chem., 63, 3497 (1998).
