ChemInform Abstract: Metal‐Stabilized Rare Tautomers of Nucleobases. Part 2. 2‐Oxo‐4‐hydroxo Form of Uracil: Crystal Structures and Solution Behavior of Two Platinum(II) Complexes Containing Iminol Tautomers of 1‐Methyluracil.

Abstract A model for a metal‐assisted tautomerization of the pyrimidine model nucleobase 1‐methyluracil is presented which, by analogy, could account for mutagenic AT → GC or GC → AT transition in DNA.
