Montmorillonite K 10 (clay) catalyzed hydrolysis of aryl-substituted α,β-difluoroallyl alcohols leading to (Z)-α-fluoro-β-aryl-substituted acrylaldehydes

Aryl-substituted aα,β-difluoroallyl alcohols 1 were readily hydrolyzed in the presence of a catalytic amount of montmorillonite K 10 (clay) in hexane at reflux temperature for 1 h to give the corresponding (Z)-α- fluoro-β-aryl-substituted acrylaldehydes 2
