Abstract

Irradiation of 1-methyl-4, 6-diphenylpyrimidin-2 (1H)-one (1a) in acyclic or cyclic ethers afforded the C–C bonded 1: 1-adducts (2a–c) of 1a and ether via intermolecular hydrogen abstraction of the excited imino nitrogen of 1a, while irradiation of 1-phenyl-4-(3- ethoxypropyl)-6-methylpyrimidin-2 (1H)-one (1g) gave 1-phenyl-4, 6-dimethylpyrimidin-2 (1H)-one (1d) via intramolecular hydrogen abstraction of the excited imino nitrogen of 1g, ...
