The peroxy radical can form a six-member endoperoxide via the transition state TS-endo, which subsequently adds an O2 to form a six-oxygen containing peroxy radical O6-RO2. This molecule can undergo a fast 1,4 aldehydic H-shift to form O6-hydroperoxide via the transition state TS-1,4 H-shift, which subsequently adds an O2 to form an eight-oxygen containing peroxy radical O8-RO2.
