Structure and properties of leucoflavin derivatives obtained through flavinsensitized photodecarboxylation of phenylacetate ions are described. The photoreduction of flavin with phenylacetate as donor is shown to be a quantitative photoalkylation, the benzyl residue entering either position 5 (nitrogen) or the bridge position 4a (carbon) of the flavin nucleus, depending on the conditions. The isomers were isolated, and identified by IR., NMR., and elementary analysis. The benzyl residue migrates from N(5) to C(4a) upon heating.
