5,5'-Diuracilyl Species from Uracil and
Not only UV radiation can bring about the dimerization of the pyrimidine nucleobase uracil, a metal ion can as well! The reaction proceeds by a reductive elimination process of two cis-oriented uracil entities, each bonded to Au(III) through C5 [Eq. (a)]. R/R'=H/CH(3), CH(3)/CH(3), H,C(5)H(9)O(4)
