{ALF}

{ALF} Mild catalyst for the formation of 1,3-dithianes from carbonyl compounds with 1,3-Propanedithiol, A15261: Tetrahedron, 58, 7897 (2002), and of 1,3-oxathiolanes with 2-Mercaptoethanol, A15890: Synlett, 1535 (2002).

{ALF} Also catalyzes intramolecular Diels-Alder reactions, with microwave irradiation; the catalyst is potentially reusable: Tetrahedron Lett., 41, 8639 (2000).

{ALF} Catalyzes the dehydration of aldoximes to nitriles; ketoximes undergo the Beckmann rearrangement to give amides or lactams: Indian J. Chem., 41B, 154 (2002).

{ALF} Superior to Indium(III)­ chloride, L18758, for the sulfonylation of both activated and deactivated aromatic rings with arylsulfonyl chlorides: Synlett, 830 (2001).

{ALF} Catalyst for hetero Diels-Alder reactions, e.g. of 1-Methoxy-3-trimethyl­siloxy-1,3-butadiene, L14672 with imines: Tetrahedron Lett., 40, 5621 (1999):

{ALF} Catalyst for efficient acylation of alcohols, phenols and amines, which can be acetylated in high yield with 0.1 mol% of catalyst: Synlett, 1743 (1999).

{ALF} For a brief feature on uses of this reagent in synthesis, see: Synlett, 899 (2003).

{ALF} Effective catalyst for tetrahydropyranylation and depyranylation of alcohols: Tetrahedron Lett., 43, 7975 (2002).

{ALF} Superior to several other metal triflates in the Fridel-Crafts reaction of aromatic compounds with Methyl­ trifluoropyruvate, B21589: Synlett, 555 (2004).
