Scandium trifluoromethanesulfonate C화학적 특성, 용도, 생산

개요

Scandium trifluoromethanesulfonate, commonly called Scandium(III) triflate, is a chemical compound with formula Sc(SO3CF3)3, a salt consisting of scandium cations Sc3+ and triflate SO3CF3? anions.
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.

White powder

용도

Scandium(III) trifluoromethanesulfonate is widely used as a catalyst in hydrothiolation, selective two-electron reduction of oxygen by ferrocene derivatives and vinylogous Fridel-crafts alkylation of indoles and pyrrole in water. It is involved in the Mukaiyama aldol addition and stereochemically catalyzes the radical polymerization of acrylates. It acts as a Lewis acid catalyst and used in the synthesis of bullvalone via a stabilized sulfur ylide.
