Description

MilliporeSigma Sigma Organics products encompass a wide range of quality reagents, solvents, catalysts, and building blocks for organic synthesis. From benchtop discovery to process development and scale-up, Sigma Organics solutions are built to meet the needs of synthetic chemists.

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'saS,5'saS)-2,6-bis[4'sa-(triisopropylsilyl)oxymethyl-5'sa-phenyl-1'sa,3'sa-oxazolin-2'sa-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.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 +a-cyanoketones.Combination with triethylsilane to reductively open functionalized pyranoside rings. The key steps of synthesis of bullvalone via a stabilized sulfur ylide.
