Abstract

During our study2 of the stannylcupration of acetylenic ethers we required [2J3C]-l for mechanistic studies. Existing methods3 for the synthesis of acetylenic ethers involve dehydrohalogenation of 2-halo, 4 1, a-dihalo vinyl ether^,^ or haloacetals6 using KOH, NaNH2, or n-BuLi. These procedures are incompatible with labile functional groups and, if applied to the preparation of 13C-labeled compounds, would require regiospecific ...
