Chloromethyl-lithium generated in situ, reacts at –78 °C with ketones (5) to afford, after lithiation with lithium naphthalenide, β-oxidoalkyl-lithium compounds (1), which on reaction with electrophiles (deuterium oxide, dimethyl disulphide, carbon dioxide, cyclohexanone, and allyl bromide) yield bifunctionalized compounds (6).
原位生成的氯甲基锂在–78°C下与酮(5)反应,在用萘化锂锂化后,得到β-氧化烷基-锂化合物(1),该化合物在与亲电子试剂(氧化氘,二甲基二硫化物,碳,二氧化碳,环己酮和烯丙基溴)生成双官能化化合物(6)。
