Application: Scandium(III) triflate was used as a catalyst in:
• Hydrothiolation reaction of aromatic and aliphatic thiols.
• Selective two-electron reduction of O2 by ferrocene derivatives.
• Vinylogous Friedel-Crafts alkylation of indoles and pyrroles in water.
• Synthesis of β-cyanoketones.
• Combination with triethylsilane to reductively open functionalized pyranoside rings.
• The key steps of synthesis of bullvalone via a stabilized sulfur ylide.
General description: Scandium(III) triflate is an extremely active, efficient, recoverable and reusable acylation catalyst. Its an important catalyst for the Friedel-Crafts acylation, Diels-Alder reactions and other carbon-carbon bond-forming reactions. It also stereochemically catalyzes the radical polymerization of acrylates. Scandium(III) triflate complex of (4′S,5′S)-2,6-bis[4′-(triisopropylsilyl)oxymethyl-5′-phenyl-1′,3′-oxazolin-2′-yl]pyridine has been employed as catalyst for the asymmetric Friedel-Crafts reaction between substituted indoles and methyl (E)-2-oxo-4-aryl-3-butenoates.
