Yan, Si-Shun,Wu, Dong-Shan,Ye, Jian-Heng,Gong, Li,Zeng, Xin,Ran, Chuan-Kun,Gui, Yong-Yuan,Li, Jing,Yu, Da-Gang
, p. 6987 - 6992 (2019/08/26)
An effective Cu-catalyzed selective formal carboxylation of C-F bonds with an atmospheric pressure of CO2 is reported. A variety of gem-difluoroalkenes, gem-difluorodienes, and α-trifluoro-methyl alkenes show high reactivity and selectivity for
An efficient synthesis of (Z)-α-fluorochalcones via the palladium-catalyzed cross-coupling reaction of (Z)-α-fluorocinnamoyl chloride with boronic acids

An efficient synthesis of α-fluorochalcones (1,3-diphenyl-2- fluoroprop-2-en-1-one) based on the Suzuki-Miyaura palladium-catalyzed cross-coupling reaction of arylboronic acids with α-fluorocinnamoyl chlorides in the presence of Cs2CO3/su
A novel reaction of β,β'-dihydroxy acids or esters with vanadium(V) trichloride oxide. New entry to the stereoselective synthesis of α-fluoro- α,β-unsaturated acids and esters
Ishihara, Takashi,Shintani, Atsuhiro,Yamanaka, Hiroki
, p. 4865 - 4868 (2007/10/03)
β,β'-Dihydroxy carboxylic acids and esters, readily prepared from dibromofluoroacetate and aldehydes, underwent deoxygenation, followed by elimination of aldehyde by the action of vanadium(V) trichloride oxide at the reflux temperature of chlorobenzene fo
Preparation et spectres de RMN, H, F et C-13 d'esters α-fluoro-cinnamiques para- et meta-substitues
Elkik, Elias,Francesch, Charlette
, p. 423 - 428 (2007/10/02)
In this publication we present H, F and C-13 NMR spectra of a series of para (11 examples) and meta (7 examples) substituted α-fluoro-Z-cinnamic esters and their corresponding acids.We also discuss the characteristics and scope of the various preparation
