A reaction of nitrones with 1,2‐dibromotetrafluoroethane affording bromodifluoroethyl‐substituted hydroxylamines is described. The process is performed in the presence of a ruthenium photocatalyst and ascorbic acid as a stoichiometric reducing agent and is mediated by blue light irradiation. The fluroalkylation products can undergo chemoselective transformations involving either N−O or C−Br bonds furnishing
描述了硝酮与1,2-二溴四氟乙烷的反应,得到溴二氟乙基取代的羟胺。该方法在钌光催化剂和抗坏血酸作为化学计量还原剂的存在下进行,并由蓝光辐射介导。氟烷基化产物可经历涉及N-O或C-Br键的化学选择性转化,从而提供各种四氟化化合物。
