Aromatic sulfonylation can also be effected with sulfonyl chlorides: J. Org. Chem., 64, 6479 (1999). At 0.1-0.5 mol%, catalyzes the acylation of primary and secondary alcohols with anhydrides in high yield under mild conditions: J. Org. Chem., 66, 8926 (2001); see also Synthesis, 2091 (2001).

Catalyzes the Michael-type addition of a variety of primary and secondary aliphatic amines to ɑ,ß-unsaturated compounds (acrylates, etc.) to give the saturated amino derivatives: Synlett, 720 (2003). The Ritter reaction of various nitriles with tert-alcohols to give tert-alkyl amides has been accomplished in high yield in the presence if a cataytic acmount of Bi(OTf)3: Tetrahedron Lett., 47, 8699 (2006). It is also effective in inducing a direct catalytic three-component Mannich reaction of an aldehyde, an amine and a ketone in aqueous media to give a ß-amino ketone: Tetrahedron Lett., 47, 8457 (2006).
