In the presence of GaCl3 and 2,6-di(tert-butyl)-4-methylpyridine, alpha-monosubstituted silyl enol ethers were alpha,alpha-diethynylated with a chlorosilylacetylene in one step. An analogous reaction using a silylacetylene gave alpha,alpha-diethenylated ketones. (c) 2006 Elsevier Ltd. All rights reserved.
