摘要：

The oxidation of 1-hexene and cyclohexene by molecular oxygen catalyzed by the iridium complexes [Ir(CH3CN)(4)NO2](A)(2) (A=PF6 (1) or BF4 (2)) has been studied in acetonitrile under P(O-2)=20 atm, T=120 degreesC, substrate/catalyst=100, t=20 h. Both complexes are active for oxidizing 1-hexene to 1,2-epoxyhexane, 1-hexen-3-one, 2-hexenal, 1-hexen-3-ol and 2-hexen-l-ol and also oxidize cyclohexene to 2-cyclohexen-1-one, 7-oxabicyclo[4.1.0]hexane and 2-cyclohexen-l-ol. Preliminary kinetic parameters are reported for complex (1). (C) 2000 Elsevier Science B.V. All rights reserved.
