ROOCo(III) + Et3SiH → ROOSiEt3 + [HCo(III)] cat. ROOCo(III) or cat. RCo(III) R'CH=CH2 → R'CH(OOSiEt3)CH3 Et3SiH, O2 Both a Co(III)-alkyl complex and a Co(III)-alkylperoxo complex were found to catalyze triethylsilylperoxidation of alkenes with O2 and Et3SiH. On this basis, together with the nonstereoselectivity in the Co(II)-catalyzed peroxidation of 3-phenylindene and the formation of the corresponding 1,2-dioxolane from 2-phenyl-1-vinylcyclopropane (a radical clock), we propose a reasonable mechanism for the Co(II)-catalyzed novel autoxidation of alkenes with Et3SiH discovered by Isayama and Mukaiyama.
