Abstract Metal triflates have been used to catalyzesynthesis of β-enamino ketones or pyrroles from amines and 1,3-dicarbonyl or 1,4-dicarbonyl compounds undersolvent-freeconditions, respectively. Among different metal triflates screened, 0.5 mol% Ga(OTf)3 efficiently promoted the reactions to give excellent yields. In addition, the catalyst could be recovered easily after the reactions and reused
