Stereoselective synthesis of 1-bromo-(or 1-chloro-) 1,1-difluoro-2-alkenes
Tellier, Frederique,Sauvetre, Raymond
, p. 79 - 82 (1996)
A highly regio- and stereo-selective method for the introduction of a bromo- (or chloro-) difluoromethylene group into various unsaturated systems is described. The key step is the treatment of 1,1-difluoro-1-alken-3-ols with thionyl bromide (or chloride).
Straightforward synthesis of α,β-unsaturated acids and derivatives
Tellier, Frederique,Sauvetre, Raymond
, p. 5433 - 5436 (2007/10/02)
A general C2 vinylic homologation from carbonyl compounds (aldehydes or ketones) which leads to various α,β-insaturated acids, esters and amides, is described.
Reaction de CF2=CH2 avec les organolithiens . Une nouvelle preparation du difluorovinyllithium
Sauvetre, R.,Normant, J. F.
, p. 957 - 958 (2007/10/02)
2,2-Difluorovinyllithium has been prepared in quantitative yield from CF2=CH2 and sec.butyllithium at low temperature.Reaction of 2,2-difluorovinyllithium with carbonyl groups gives the corresponding alcohols.
