• Selective oxidant which can be used in dichloromethane to convert primary alcohols to aldehydes: Tetrahedron Lett., 399 (1979). Can also be used catalytically in combination with Sodium percarbonate, A16045, as co-oxidant for conversion of allylic and benzylic alcohols to aldehydes under phase-transfer conditions: Tetrahedron Lett., 35, 1989 (1994). Under the same conditions, ɑ-functionalized benzylic alcohols undergo oxidative cleavage: Synth. Commun., 25, 2051 (1995).
