Description General description Scandium(III) triflate is an important catalyst for 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. Application Scandium(III) triflate was used as catalyst in the following studies: • 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. It was also used with triethylsilane to reductively open functionalized pyranoside rings and in the key step of synthesis of bullvalone via a stabilized sulfur ylide.
