PRODUCTION OF COMPOUNDS COMPRISING CF30 GROUPS

The present invention relates to a process for the preparation of compounds containing CF3O groups using compounds containing at least one group Y, in which Y=—Hal, —OSO2(CF2)zF, —OSO2CzH2z+1 (z=1-10), —OSO2F, —OSO2Cl, —OC(O)CF3— or —OSO2Ar, to a process for the preparation of compounds containing CF3O groups using KOCF3 and/or RbOCF3, and to novel compounds containing CF3O groups, and to the use thereof.

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.
