Pj. Baricelli et al., Catalytic oxidation of 1-hexene and cyclohexene with molecular oxygen by iridium nitro complexes, J MOL CAT A, 164(1-2), 2000, pp. 77-84
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 be
en studied in acetonitrile under P(O-2)=20 atm, T=120 degreesC, substrate/c
atalyst=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 a
nd 2-cyclohexen-l-ol. Preliminary kinetic parameters are reported for compl
