In this report, we identify xanthate salts as a unique class of visible-light-excitable alkyl radical precursors that act simultaneously as strong photoreductants and alkyl radical sources. Upon direct photoexcitation of xanthate anions, efficient deoxygenative alkenylation and alkylation of a wide range of primary, secondary, and tertiary alcohols have been achieved via a one-pot protocol, avoiding
在本报告中,我们将黄原酸盐确定为一类独特的可见光可激发烷基自由基前体,它们同时充当强光还原剂和烷基自由基源。在黄原酸盐阴离子的直接光激发下,通过一锅法实现了多种伯醇、仲醇和叔醇的有效脱氧烯基化和烷基化,避免了任何光催化剂。该方法具有广泛的底物范围和良好的官能团耐受性,可实现复杂分子的后期功能化。
