F/Cl substitution with rearrangement initiated by the Lewis acid AlCl3 in α,ω[2-(F-alkyl)ethenyl]acyl derivatives: highly stereospecific trans-CF2CHCHto trans-CFCHCH(Cl) transformation
摘要:
The action of AlCl3 on C8F17-CH=CH-(CH2)8-COCl (E isomer) leads, under mild conditions and after ethanolysis, to the formation of C7F15-CF=CH-CH(Cl)(CH2)8-COOEt, as a result of the -CF2-CH=CH- to -CF=CH-CH(Cl)- transformation which proceeds in high yield (70%) and with high stereospecificity: the isolated compound consists of the Z isomer (H and F trans).

The synthesis and characterization of various mono- and 1,1′-bis-[ω-(F-alkyl)acyl]ferrocenes, 1,1′-bis-[ω-(F-alkyl)alkyl]ferrocenes and 1,1′-bis-[ω-(F-alkyl)-α-(hydroxy)-alkyl]ferrocenes are described (where F-alkyl denotes perfluoroalkylation). The [(F-alkyl)acyl]ferrocenes were obtained by Friedel-Crafts acylation of ferrocene with (F-alkyl)acyl chlorides. The (F-alkyl)alkyl and (F-alsyl)-α-(hydroxyl)alkyl
