reagents to improve the chemoselectivity. To overcome the above problems, we present a photochemical hydroxyazidation of alkenes via Mn-mediated ligand-to-metal charge transfer (LMCT) in O2, which activates N3– to •N3 and incorporates O2 to be used as an oxygen source in the hydroxyazidation products. Broad alkene range and step-economy chemistry for the hydroxyazidation transformation were also demonstrated
最先进的烯烃羟基叠氮化策略,产生β-叠氮醇和β-叠氮过氧化物的混合物,必须依靠膦试剂来提高化学选择性。为了克服上述问题,我们提出了一种通过 O 2中锰介导的配体到金属电荷转移 (LMCT) 进行烯烃的光化学羟基叠氮反应,将 N 3 –活化为•N 3并结合 O 2用作氧来源为羟基叠氮化产物。还证明了羟基叠氮化转化的广泛烯烃范围和步骤经济化学。
