alcohol and amine derivatives catalyzed by 2,4,5,6-tetra(9H-carbazol-9-yl)isophthalonitrile (4CzIPN) was developed. This reaction delivered δ-fluoromethylated free alcohols and amines with in situ deprotection of benzyl protecting group under mild irradiation conditions. 4CzIPN was found to be a competent metal-free photoredox catalyst for activating several types of fluoromethylation reagents including
开发了由2,4,5,6-四(9 H-咔唑-9-基)间苯二甲腈(4CzIPN)催化的苄基保护的均丙醇和胺衍生物的加氢三氟甲基化。该反应递送δ-氟甲基化的游离醇和胺,并在温和的辐射条件下原位去保护苄基保护基。已发现4CzIPN是一种有效的无金属光氧化还原催化剂,可通过氧化猝灭活化CF 3 SO 2 Cl,Togni试剂和2-溴-2,2-二氟乙酸酯,以及通过CF 3 SO 2 Na活化几种类型的氟甲基化试剂。还原淬灭,以使简单的烯烃和迈克尔受体直接进行氢三氟甲基化。

of Csp3-bromides. Specifically, a copper/photoredox dual catalytic system for the coupling of alkylbromides with trifluoromethyl groups is presented. This operationally simple and robust protocol successfully converts a variety of alkyl, allyl, benzyl, and heterobenzyl bromides into the corresponding alkyl trifluoromethanes.
