Abstract In this work it is shown that iron (III) and gold (I) triflimide efficiently catalyze the hydroaddition of a wide array of nucleophiles including water, alcohols, thiols, amines, alkynes, and alkenes to multiple C [BOND] C bonds. The study of the catalytic activity and selectivity of iron (III), gold (I), and Brønsted triflimides has unveiled that iron (III) triflimide [Fe (NTf 2) 3] is a robust catalyst under heating conditions, whereas gold (I) triflimide, even ...
