A mild, functional group tolerant method of the preparation of phenyl esters from aryl chlorides via palladium-catalyzed carbonylation is described using atmospheric pressure of carbon monoxide. Phenyl esters are shown to be useful acylating agents, delivering libraries of carbonyl derivatives, including alkyl, allyl and thioesters, under very mild conditions. Direct preparation of alkyl esters and
描述了使用一氧化碳的大气压从芳基氯化物通过钯催化的羰基化制备苯基酯的温和的,具有官能团耐受性的方法。已显示苯基酯是有用的酰化剂,其在非常温和的条件下递送羰基衍生物的库,包括烷基,烯丙基和硫代酯。还证明了直接制备烷基酯和羧酸的方法,提供了在不使用加压反应器的情况下从芳基氯化物制备甲酯和乙酯的第一种方法。
