form

powder

Application

  • Reusable and eco-friendly catalyst for synthesis of quinoxalines

Catalyst for:
  • Baeyer-Villiger oxidation of ketones
  • Diphenylmethane transformations
Silica supported boron trifluoride can be used as a catalyst in the preparation of:
  • The O- and C-alkylated phenols.[1]
  • Arylazo-1-naphthol derivatives.[2]
  • 1,2,4,5-Tetrasubstituted imidazoles through a one-pot reaction of amine, benzil and aromatic aldehydes.[3]
  • 14-Aryl or alkyl-14H-dibenzo[a,j]xanthenes by the reaction of 2-naphthol with aldehydes.[4]
  • Tetrahydropyridines through a one-pot reaction of aldehydes, amines with β-ketoester.[5]

Baeyer-Villiger Oxidation Reaction

The Baeyer-Villiger oxidation is the oxidative cleavage of a carbon-carbon bond adjacent to a carbonyl, which converts the ketones to esters and the cyclic ketones to lactones.
