Photochemical dehydrogenation of 5, 6-dihydropyrimidines.

I Rosenthal, S Sasson, D Elad.   

Abstract

5, 6-Dihydropyrimidines can be oxidized photochemically to the original pyrimidines with light of lambda greater than 300 nm in the presence of transition metal salts which act as sensitizers. A hydrogen atom abstraction by hydroxyl radical is suggested as the reaction mechanism.
