The reaction of 1,1,1,5,5,5-hexafluoroacetylacetone with push-pull enamines having a methyl group at the alpha-position was investigated. It was found that the reaction is sensitive both to the structure of enamines and to reaction conditions. As a result, a set of bistrifluoromethyldialkylanilines and ethyl bistrifluoromethylsalicylate was prepared. Plausible mechanisms and factors influencing the course of the reaction are discussed.

An efficient method for the direct oxidation of various N-aryl pyrrolidines to the corresponding lactams using α- angelica lactone as catalyst has been demonstrated. Di-oxygen was employed as the terminal oxidant and oxygen source.
