A practical and precise method for visible-light-promoted deoxygenative deuteration of common aliphatic alcohols using D2O as the deuterium source is reported. Upon intermediacy of xanthate anions, a variety of primary, secondary, and tertiary alcohols can be facilely transformed into deuterioalkanes with excellent D-incorporation at predicted sites. The deoxygenation and deuteration sequence is catalyzed
报道了一种使用 D 2 O 作为氘源的可见光促进的常见脂肪醇脱氧氘化的实用且精确的方法。在黄原酸阴离子的中介作用下,各种伯醇、仲醇和叔醇可以很容易地转化为氘代烷烃,并且在预测位点具有出色的 D-结合。脱氧和氘化序列由原位形成的氘代2-巯基吡啶催化,它发挥着氘原子转移催化剂和电子穿梭的双重作用。
