Although α‐alkylation of ketones with primary alcohols by transition‐metal catalysis is well‐known, the same process with secondary alcohols is arduous and complicated by self‐condensation. Herein a well‐defined, high‐valence cobalt(III)‐catalyst was applied for successful α‐alkylation of ketones with secondary alcohols. A wide‐variety of secondary alcohols, which include cyclic, acyclic, symmetrical
尽管通过过渡金属催化将酮与伯醇进行α-烷基化是众所周知的,但与仲醇进行相同的过程却很艰巨,并且由于自身缩合而变得复杂。本文将定义明确的高价钴(III)催化剂用于成功地将仲醇与酮进行α-烷基化反应。各种各样的仲醇,包括环状,无环,对称和不对称化合物,都被用作烷基化剂来生产β-烷基芳基酮。
