1,3-Bis(4-methoxyphenyl)cyclohexane-1,3-diyl cation radical: divergent reactivity depending upon electron-transfer conditions

1,3-Bis(4-methoxyphenyl)cyclohexane-1,3-diyl cation radical gives 1,5-bis(4-methoxyphenyl)bicyclo[3.1.0]hexane through 1,3-bis(4-methoxyphenyl)cyclohexane-1,3-diyl when generated by photoinduced electron transfer, but gives 4,4″-dimethoxy-m-terphenyl when generated by using one-electron oxidant, demonstrating its divergent reactivity depending upon the electron-transfer conditions employed.
