  direct trifluoromethylation of a variety of aliphatic alcohols using a hypervalent iodosulfoximine reagent afforded the corresponding ethers in moderate to good yields (14–72 %). Primary, secondary, and even tertiary alcohols, including examples derived from natural products, underwent this transformation in the presence of catalytic amounts of zinc bis(triflimide). Typical reaction conditions involved

  使用高价碘亚磺酰亚胺试剂对各种脂肪醇进行直接三氟甲基化，可以以中等至良好的收率（14-72％）提供相应的醚。伯，仲，甚至叔醇，包括衍生自天然产物的实例，在催化量的双（三氟酰亚胺）锌存在下进行了这种转化。典型的反应条件包括6.0当量的醇与1.0当量的试剂的纯净混合物，大多数反应在2小时内用2.5 mol％的路易斯酸催化剂完成。此外，提供了实验证据表明，通过醇与碘原子的配位以及随后的还原消除，可以形成C-O键。

  Hydrolytically stable and easy to handle trifluoromethyl triflate was found to be a liquid reservoir of 'masked' difluorophosgene. Anhydrous F(-) sources cleave the S-O bond in trifluoromethyl triflate yielding quantitatively the trifluoromethanolate salts, being useful trifluoromethoxy group carriers. Reaction of trifluoromethanolates with in situ generated from o-trimethylsilylphenyl triflate benzyne leads to (trifluoromethoxy)benzene and fluorobenzene (ratio 85:15). Whereas an addition of trifluoromethanethiolate anion across a triple bond of benzyne leads to [(trifluoromethyl)sulfanyl]benzene solely. (C) 2007 Elsevier Ltd. All rights reserved.
• A deeper insight into direct trifluoromethoxylation with trifluoromethyl triflate

  Commercially available fluorides (silver fluoride and n-tetrabutylammonium triphenyldifluorosilicate), combined with TFMT, allow a simple generation, in situ, of silver and n-tetrabutylammonium trifluoromethoxides which were able to react with electrophilic substrates. Silver trifluoromethoxide, which is usually more efficient than n-tetrabutylammonium trifluoromethoxide, converts, under mild conditions, primary aliphatic bromides and iodides, as well as primary and secondary benzylic or allylic bromides to the corresponding trifluoromethoxylated compounds. Several trifluoromethyl ethers, which could be valuable building-blocks, were prepared in such a way. (C) 2009 Elsevier B.V. All rights reserved.
