Geminal Difunctionalization: The alkylation–halogenation of ketosulfoxonium ylides in the presence of alkyl halides is described. The method furnishes several gem-difunctionalized haloketones in good yields. Replacing alkyl halides with a mixture of electrophilic halogen species and various halide anions led to gem-dihalogenated ketones containing a combination of the same or two different halogens. Kinetic isotopic effects, as well as reaction kinetic experiments, give insight to the mechanism of these reactions.

Y鎓叶立德的α，α-烷基化-卤化和二卤化。双功能双酮的直接制备

Geminal Difunctionalization（双官能双功能化）：描述了在烷基卤化物的存在下，酮基ox氧鎓烷基化物的烷基化-卤化反应。该方法以良好的产率提供了几种宝石双官能化的卤代酮。用亲电子卤素物质和各种卤化物阴离子的混合物代替烷基卤化物，导致宝石二卤代酮含有相同或两种不同卤素的组合。动力学同位素效应以及反应动力学实验使人们洞悉了这些反应的机理。
