donium tetrafluoroborate in methanol regiospecifically yield the naphthalen-1- and -2-yl ethers but afford scrambled 1- and 2-phenylnaphthalene Friedel-Crafts products. It is demonstrated that singlet naphthyl cations account for the formation of the naphthyl ethers, but that the cine substitution is most likely to be due to the intermediacy of triplet naphthyl cations. According to the experiments
萘-1-基(苯基)碘四氟硼酸盐和萘-2-基(苯基)碘四氟硼酸盐在甲醇中的光化学溶剂分解区域特异性地产生萘-1-和-2-基醚,但提供杂乱的1-和2-苯基萘Friedel -工艺品产品。证明单线态萘基阳离子导致了萘基醚的形成,但电影取代最有可能是由于三线态萘基阳离子的中介作用。根据这里报道的实验,单线态萘基阳离子的能量低于它们的三线态异构体。甲醇中阳离子的高水平 MO 计算支持这一发现。

cross-coupling of (hetero)aryl bromides with fluorinated alcohols using the commercially available precatalyst tBuBrettPhos Pd G3 and Cs2CO3 in toluene. This Pd-catalyzed coupling features a short reaction time, excellent functional group tolerance, and compatibility with electron-rich and -poor (hetero)arenes. The method provides access to 18F-labeled trifluoroethyl ethers by cross-coupling with [
在本文中,我们报告了一种高效的方案,可使用市售的预催化剂t BuBrettPhos Pd G3和Cs 2 CO 3在甲苯中将(杂)芳基溴化物与氟化醇交叉偶联。这种钯催化的偶联反应具有反应时间短,对官能团的耐受性强以及与富电子和贫电子(杂)芳烃相容的特点。该方法通过与[ 18 F]三氟乙醇交叉偶联而获得18 F-标记的三氟乙基醚。

An efficient synthesis of fluorinated alkyl and aryl ethers was achieved by the use of s-triazene derived fluorinated reagent 2,4,6-tris-(2,2,2-trifluoro-ethoxy)-[1,3,5] triazene (TriTFET).
An efficient copper-catalyzed Chan–Lam reaction of trifluoroethanol with a variety of aryl- and heteroaryl boronicacids has been developed. This research provides a practical method to synthesize trifluoroethyl aryl ethers in moderate to good yields under mild conditions.
