Reductive addition of polychloroalkanes to fluoroketones

Abstract The nucleophilic trichloromethylation of fluoroketones has been performed by reductive addition of CCl 4 under the action of amalgam: Trichloroalkanes ( II ) were involved in a similar reaction with hexafluoroacetone; however perfluoropinacol was a main product in the case of CCl 3 Me: The trichloromethylcarbinols ( I ) were used in the synthesis of perfluorinated tertiary alcohols and trifluoromethylsubstituted 1,1-dichlorooxiranes.
