The invention relates to compounds having the general formula (I), the method of preparation thereof and the use thereof in organic radical synthesis. The invention also relates to compounds having the formula (II), the method of preparation thereof and a method for preparing compounds having the formula (VIII).
The reactions of N-benzoyl- and N-acetyl-1-chloro-2,2,2-trifluoroethylamines with various carbon-nucleophiles gave the corresponding 1-substituted N-acyl-2,2,2-trifluoroethylamines in good yields and the efficient reactivity was applied on the synthesis of 2-acylamino-2-trifluoromethylethanol derivative.
[GRAPHICS]S-[1-(N-Acetylamino)-2,2,2-trifluoroethyl]-O-ethyl dithlocarbonate (6), a readily available xanthate, adds efficiently to various functionalized olefins to give the corresponding adducts 8 via a radical chain reaction initiated by a small amount of lauroyl peroxide.
