Evaluation of efficient and practical methods for the preparation of functionalized aliphatic trifluoromethyl ethers

The "chlorination/fluorination" technique for aliphatic trifluoromethyl ether synthesis was investigated and a range of products with various functional groups was prepared. The results were compared with oxidative desulfurization-fluorination of xanthates with the same structure.
Synthesis of trifluoromethyl ethers and difluoro(methylthio)methyl ethers by the reaction of dithiocarbonates with IF5-pyridine-HF

Trifluoromethyl ether and difluoro(methylthio)methyl ether of phenols and aliphatic alcohols were selectively synthesized from the corresponding dithiocarbonates. When IF5-pyridine-HF was used alone in the reaction of the dithiocarbonate, the difluoro(methylthio)methyl ether was selectively formed. On the other hand, by the additional use of Et3N-6HF with IF5-pyridine-HF, trifluoromethyl ether was formed selectively. Various functional groups such as ester, ether, amide, and acetonide could tolerate the reaction conditions, and various functionalized difluoro(methylthio)methyl ethers and trifluoromethyl ethers were synthesized.
Versatile application of trifluoromethyl triflate

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.
