在红光（690 nm）照射下，醌类化合物在金属酞菁存在下被硫醇类化合物转化为对苯二酚。反应通过酞菁三重态和醌之间的电荷分离进行。产物决定步骤是醌阴离子自由基的质子化，如通过使用更多酸性硫醇或添加酸加速反应的事实所指示的。
Under the irradiation of red light (690 nm), quinones were converted to hydroquinones by thiols in the presence of metallophthalocyanines. The reaction proceeded via the charge separation between the triplet state of phthalocyanine and the quinone. The product determining step was protonation of the quinone anion radical, as indicated by the fact that the reaction was accelerated by the use of more acidic thiols or addition of an acid.
