Improved results in epoxidations with H₂O₂ in the presence of pyrazole have been reported by Herrmann: J. Organomet. Chem., 555, 293 (1998), and by Sharpless with pyrazole, pyridine or 3-cyanopyridine: Tetrahedron Lett., 40, 3991 (1999); J. Org. Chem., 65, 8651 (2000); see also Tetrahedron Lett., 39, 8521 (1998). For use in the Baeyer-Villiger oxidation of ketones, see: Angew. Chem. Int. Ed., 37, 1198 (1998); the reaction can also be carried out with H₂O₂ in ionic liquids at room temperature: Tetrahedron Lett., 44, 8991 (2003).
