Abstract

The reaction of trans-K [Au (CN) 2Cl2] with 1, 3-dimethyluracil (1, 3-DimeU) gives trans-K [Au (CN) 2Cl (1, 3-DimeU−–C5)](1) which contains the 1, 3-dimethyluracil-5-yl entity (1, 3- DimeU−–C5) bound to AuIII. Complex 1 represents the first example of an X-ray structurally characterized organogold (III) complex of a nucleobase. Further reaction with purine model nucleobases (nb) such as 9-ethylguanine (9-EtGH), 9-methyladenine (9-MeA), and 1- ...
