Ag(i)-Catalyzed oxidative decarboxylation of difluoroacetates with activated alkenes to form difluorooxindoles†
Abstract
A silver-catalyzed oxidative decarboxylative gem-difluoromethylenation of difluoroacetates with activated alkenes under mild reaction conditions has been developed. This radical cascade reaction provides a new method for the construction of a variety of gem-difluoromethylenated oxindoles.
