Photolysis of 5,6-iodo-1,3-dimethyluracil in benzene and in furan
Abstract
In contrast to 1,2-di-iodobenzene, photolysis of 5,6-di-iodo-1,3-dimethyluracil in benzene and in furan rapidly gives products derived from a radical intermediate and none derived from the corresponding pyrimidyne. 5-Iodo-1,3-dimethyluracil radical is believed to be the precursor of all the identified products. The scope and mechanism of these photoreactions are discussed.
