One More Stable Enol: 2,2-Bis[(trifluoromethyl)thio]ethenol. Synthesis and Reactivity1
摘要:
The efficient synthesis of 2,2-bis[(trifluoromethyl)thio]acetaldehyde by acidic hydrolysis of 1-(N,N-diethylamino)-2,2-bis[(trifluoromethyl)thio]ethene is presented. The tautomeric equilibrium for the compound obtained is strongly shifted to enol form, so with silver nitrate in water solution a corresponding silver salt is formed that reacts with ethyl bromide to ethyl 2,2-[(trifluoromethyl)thio]vinyl ether. The enol reacts with amines to form respective enamines. IR, MS, H-1, C-13, and F-19 NMR data for compounds synthesized are given to support their structure elucidation.

Reaction of CFnCl3−nSCl with (C2H5)3N gives (CFnCl3−nS)2C= CHN(C2H5)2, whereby the yields decrease with decreasing n. Spectroscopical and physical data as well as results of some biological tests are presented.

The formation of bis-beta,beta-(CF3S)-substituted enamines depends on the molar ratio of the starting materials. In this way, the yield of 1,1-bis(trifluoromethylthio)-2-(N,N-diethylamino)ethene was improved. The influence of amine structure on the formation of enamines is discussed.
