Abstract
An examination of the kinetics of the photoreduction of zinc tetraphenylporphin by benzoin is reported. The products are successively the dihydro‐ (chlorin) derivative; a tetrahydro‐derivative and possibly a hexahydro compound as well. It is demonstrated that the primary requirement is the photoactivation of the benzoin; a secondary reaction, involving photoactivated porphyrin as well, is also demonstrated. The quantum yield based on light absorbed by benzoin varies between 0.01 and 0.06.Keywords
