light-emitting diodes. A method for the synthesis of gem-difluorohomoallylic alcohols by the substitution of iodine in the iododifluoromethyl group by a vinyl fragment is described. The reaction proceeds via an intramolecular iodine atom transfer followed by β-elimination. The reaction is performed in the presence of an iridium photocatalyst, fac-Ir(ppy)3, and triphenylphosphine under irradiation with light-emitting
摘要 描述了通过用乙烯基片段取代碘二氟甲基中的碘来合成宝石-二氟均烯丙基醇的方法。该反应通过分子内碘原子转移然后进行β-消除进行。该反应在铱光催化剂,fac -Ir(ppy)3和三苯膦的存在下,在用发光二极管照射下进行。 描述了通过用乙烯基片段取代碘二氟甲基中的碘来合成宝石-二氟均烯丙基醇的方法。该反应通过分子内碘原子转移然后进行β-消除进行。该反应在铱光催化剂,fac -Ir(ppy)3和三苯膦的存在下,在用发光二极管照射下进行。
