Electron-transfer photooxygenation of 1,1,2,2-tetraphenylcyclopropane with 9,10-dicyanoanthracene in oxygen-saturated acetonitrile yields 1,1,3,3-tetraphenyl-2-propen-1-ol after reduction of the intermediate hydroperoxide.The rate of reaction is significantly increased by the addition of biphenyl as a cosensitizer.
