(CH3) 3SiCF3 reacts with fluoro ketones in the presence of excess KF in CH3CN to produce alkoxides derived from formal addition of CF3-to the carbonyl carbon. These alkoxides may be isolated as such or acidified to the corresponding alcohols. Ketones to which this technique was applied include (CF3) &= 0, CF3C (0) CF2Cl, CF3C (O) CFZH, and [(CF3) 2CF] 2C= O. The last compound reads with replacement of one of ita perfluoroisopropyl ...
