Evidence is presented that contradicts an earlier finding that, in the absence of steric hindrance, the coupling reaction of alkylcarbonyloxymethyl (ACOM) halides with phenols favors acylated product. A one-step synthesis is used to generate sterically unhindered ACOM iodides, which are then reacted with several phenols to give mainly alkylated phenol.
提出的证据与较早的发现相反,在没有空间位阻的情况下,烷基羰基氧基甲基(ACOM)卤化物与
酚类的偶联反应有利于酰化产物。一步合成用于生成空间不受阻碍的ACOM
碘化物,然后使其与几种
酚反应,主要生成烷基化
苯酚。
