— The mechanism of the photooxidative dephosphorylation of menadiol diphosphate appears to be invariant with respect to three sensitizers used; namely, riboflavin, biacetyl, and menadiol diphosphate itself. The mechanism involves triplet energy transfer from the sensitizers to oxygen to yield singlet oxygen which oxidizes menadiol diphosphate. The photolysis of menadiol diphosphate in acetic acid has resulted in formation of acetyl phosphate, as determined by paper chromatography. Therefore, we have demonstrated the feasibility of our model for converting light energy into chemical potential (‘high‐energy’ phosphate bond energy or group transfer potential) in the form of acetyl phosphate.
