Abstract: A 1:1:1 stoichiometric reaction between CrO_3, aqueous HF, and quinaldine affords orange crystalline quinaldinium fluorochromate(VI) (QnFC) (C_{10}H_9NH[CrO_3F]) in 99.4% isolated yield. A highly efficient, simple, chemoselective, and environmentally benign procedure for QnFC (3 mol%) catalyzed oxidation of primary and secondary alcohols to aldehydes and ketones using 1.1 equiv of H_5IO_6 under solvent-free conditions is described.

Keywords: Periodic acid, solvent-free, oxidation of alcohols, quinaldinium fluorochromate(VI)
