dianion of phenylsulfinylacetone with alkyl halides afforded beta-keto sulfoxides, which were first chlorinated with hexachloroethane and then treated successively with KH and t-BuLi to give carboxylic acids in three-steps in moderate overall yields from the alkyl halides. This procedure affords a good method for a synthesis of carboxylic acids from alkyl halides with three-carbon elongation.
苯亚磺酰基丙酮的二价阴离子与卤代烷反应生成的β-酮亚砜,先用六氯乙烷进行氯化处理,然后依次用KH和t-BuLi处理,分三步从卤代烷中以总产率适中的方式得到羧酸。该程序为由具有三碳延伸率的卤代烷合成羧酸提供了一种很好的方法。
