Abstract
The photoreaction of 5-bromo-1,3-dimethyluracil in 1,4-xylene solution yields a mixture of 5- and 6-aryl substituted uracils. The 5-isomer is formed first and is followed by the 6-isomer, the latter being the product from protonated uracil. In the presence of initially added acid (HBr and trifluoroacetic acid) both isomers are formed simultaneously.
