Chem. Int. Ed., 30, 1636 (1991), a catalyst for clean epoxidation of alkenes with H2O2: Angew. Chem. Int. Ed., 30, 1638 (1991), and to promote the olefination of aldehydes with diazo esters: Angew. Chem. Int. Ed., 30, 1641 (1991). The activation of H2O2 in epoxidation and other reactions has been extensively studied; feature article: Chem. Commun., 479 (1999). 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).

High yield aerobic oxidation of various organonitrogen compounds has been described: e.g. pyridines to N-oxides, anilines to nitrobenzenes and sec-amines to nitrones: Tetrahedron Lett., 44, 3235 (2003).
