A general method to fluorous ponytail-substituted aromatics
摘要:
Palladium-catalyzed olefination of aryl halides led to a variety of fluorous ponytail-substituted, functionalized aryl compounds with good to excellent yields. The same chemistry was also applied to the synthesis of binaphathols bearing fluorinated ponytails. (C) 2001 Elsevier Science Ltd. All rights reserved.

Heck couplings of aryl halides with fluoroalkyl-substituted ethylenes catalyzed by Pincer Palladium complex were described. A variety of fluorous ponytail-substituted aromatics were obtained with moderate to excellent yields. Moreover, the catalyst can be easily separated from the reaction mixture by F-SPE technique and reused three times without significant loss of activity.

Copper-catalyzed decarboxylative difluoroalkylation and perfluoroalkylation of α,β-unsaturatedcarboxylicacids is described. Promoted by dialkyl phosphite, this novel reaction affords fluoroalkylated motifs with excellent stereoselectivity and broad substrate scope under mild reaction conditions from readily available fluoroalkyl iodides and bromides. Preliminary mechanism study suggests that radical
