In a previous crystallographic study of some N-arylpyrimidinones 1, we noted that: (1) C-H···O hydrogen bonds connect molecules in a linear array; (2) the charge transfer axis of the chromophore is aligned with the main symmetry operator of point groups 2

The photochemical reactions of 1-aryl-4,6-disubstituted pyrimidin-2(1H)-ones have been examined.Irradiation of 1-aryl-4,6-disubstituted pyrimidin-2(1H)-ones (1)-(6) in benzene in the presence of primary or secondary amines gave arylimine products(10)-(15)
PHOTOCHEMICAL REACTION OF PYRIMIDIN-2(1H)-ONES: INTER- AND INTRAMOLECULAR HYDROGEN ABSTRACTION BY THE NITROGEN OF IMINO GROUP

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 hyrogen 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, in addition to 2-oxo-1,3-diazabicyclohex-5-ene derivative (3g).
