Exploration of α,α-dibromo-β-dicarbonyl compounds as novel bromine agents for the conversion of alcohols to alkyl bromides under neutral conditions has been achieved. This method can be used for acid-sensitive substrates and allows the bromination of various primary and secondary alcohols to proceed at room temperature within a very short period of time.
已经探索了作为新型溴化剂的α,α-二溴-β-二羰基化合物用于在中性条件下将醇转化为烷基溴化物的方法。该方法可用于酸敏感的底物,并允许各种伯醇和仲醇的溴化在非常短的时间内在室温下进行。
