The photoreduction of 1,2-diarylcyclopropanes <B>1</B> by NaOH yielded the corresponding 1,3-diarylpropanes <B>2</B> in <I>i</I>-PrOH. The efficiency of the photoreduction was dependent on the electron deficiency of <B>1</B> and the excitation wavelength, solvent, and additive. This is a rare example of a cyclopropane serving as an electron acceptor to afford a reduction product.
