Abstract
Hafnium trifluoromethanesulfonate [Hf(OTf)4]- and scandium trifluoromethanesulfonate [Sc(OTf)3]-catalyzed conjugated addition of 3-position of indoles to several enones proceeded in acetonitrile as solvent. Especially, Hf(OTf)4 exhibited high catalytic activity and gave the conjugate addition product in good yield.
