Abstract
The oxidation of 1-hexene by molecular oxygen catalyzed by iridium(III ) complexes, [Ir(CH3CN)(5-x)Cl-x(NO2)](2-x) (x = 0, 1, or 2) has been studied in acetonitrile under P(O-2) = 1.5 atm and T = 100 degrees C. [Ir(CH3CN)(5)(NO2)](PF6)(2) oxidizes 1-hexene to 1,2-epoxyhexane. Comp lex [Ir(CH3CN)(4)Cl(NO2)]PF2 oxidizes 1-hexene to 2,3-epoxyhexane only in the presence of [IPd(PhCN)(2)(Cl)(2)] (an olefin activator). In co ntrast to the cationic complexes, the neutral complex [Ir(CH3CN)(4)Cl- 2(NO2)] oxidizes 1-hexene to 2-hexanone only in the presence of[Pd(PhC N)(2)(Cl)(2)].
