and bicyclic alcohols with dimethyl sulfoxide (DMSO) “activated” by numerous electrophiles was studied: yields of carbonyls, by-products and recovered alcohols were quantitatively determined. Pathways for carbonyl and by-product formation are presented. Generally, yields of carbonyls increase with increased steric hindrance in the alcohols. Steric effects of tertiary amines, used for basification, were
研究了由许多亲电试剂“活化”的二甲亚砜(DMSO)对伯,仲,烯丙基,苄基,受阻和双环醇的氧化作用:定量测定了羰基化合物,副产物和回收的醇的收率。介绍了羰基和副产物形成的途径。通常,羰基化合物的产率随着醇中位阻的增加而增加。还研究了用于碱化的叔胺的立体效应,其结果与建议的反应途径一致。在以前未报道的“活化剂”中,草酰氯是最有效的。羰基化合物的收率通常超过95%。亚硫酰氯也是令人满意的“活化剂”,尽管羰基的收率并不高。
