Leucoriboflavin 5′-phosphate derivatives were prepared by reductive acylation of riboflavin 5′-phosphate. These compounds were rather unstable and were easily hydrolyzed to riboflavin 5′-phosphate derivatives, regaining the yellow color. On heating with 17% hydrochloric acid, leucoriboflavin 5′-phosphate tetraacetate and monoethylformate yielded riboflavin 2′, 5′-anhydride, m.p. 300-302°. This substance was sensitive to light and formed lumichrome as the photo-decomposition product on exposure to light.
