Visible light (>450 nm) is used to efficiently cleave carboxylic acids, aminoacids, and phosphates from their N-methyl picolinium esters. Photolysis using pyrromethene dyes PM 546 and PM 597 and also coumarin 6 as photosensitizers effects release of carboxylic acids, N-protected aminoacids, and phosphates in quantitative yields. The effective rate of photorelease by the dyes, Phiepsilon, was found
