In the presence of a catalytic amount of NHC 3 (IAd, 0.1 to 5 mol %), a series of enolizable ketones as well as cyclohexanecarboxaldehyde were efficiently converted into the corresponding silyl enol ethers at 23 degrees C in THF.
发现N-杂环卡宾(NHC)催化甲硅烷基从三烷基甲硅烷基烯酮缩醛向酮的转移。在催化量的NHC 3(IAd,0.1至5摩尔%)的存在下,一系列可烯化的酮以及环己烷甲醛在23摄氏度的THF中被有效地转化为相应的甲硅烷基烯醇醚。
