The exchange reaction of α-mercurated ketones with bis(triethylsilyl)- (I) and bis(triethylgermyl)mercury (II) leads to the formation of the corresponding triethylsilyl and triethylgermyl enol ethers. O-Silylated and O-germylated enolates derived from ketones and aldehydes can be also prepared by treating mercurials I and II with appropriate α-bromo-carbonyl compounds. This new pathway also represents
α-汞化的酮与双(三乙基甲硅烷基)-(I)和双(三乙基锗基)汞(II)的交换反应导致形成相应的三乙基甲硅烷基和三乙基锗基烯醇醚。Ò -Silylated和ö -germylated从酮和醛衍生的烯醇化物可以通过将汞I和II与合适的α溴羰基化合物来制备。这一新途径也代表了制备含溴的三乙基甲硅烷基和三乙基锗基烯醇醚的最佳可用方法。总结了可用于鉴定和表征这些化合物及相关化合物的NMR和IR光谱特征。
