A novel application of highly stable Fe(OTf)3 as an efficient catalyst for the synthesis of a variety of β-enaminoketones and esters under solvent-free conditions is described. Notably, this protocol of a “green synthesis”, which produced β-enaminoketones and esters by the reaction of a variety of β-dicarbonyl compounds and primary amines, exhibits attractive properties including high yields, short
