WebAlkynyl halides serve as a source of Br + and acetylide ions in an efficient one-step preparation of alkynyl epoxides, important organic building blocks, from ... The lithium acetylide formed from the FBW reaction can also undergo transmetalation to provide zinc, copper, tin, or platinum acetylides. T. Luu, Y. Morisaki, N. Cunningham, ... WebExchange of lithium phenylacetylide onto Au (PET)18 in mild conditions is shown in Fig. S8. Notably, only the acetylide and thiolate ligands exchange in this case as no masses corresponding to lithium-for-gold exchange were observed.
