Uracil and thymine react with bensoyl chloride in acetonitrile-pyridine solution at room temperature to give first their 1-N-benzoyl (2b and 3b) and then their l-E, 3-E-dibensoyl derivatives (4a and s, respectively); <he lattercompounds are converted into the corresponding 3-E-bensoy derivatives (5a
## Abstract Laser Raman spectroscopy permits an identification of the Nโ1 and Nโ3 deprotonated tautomers of uracil and thymine and a qualitative estimation of their distribution in solution. The applicability of the method with respect to the differentiation of other heterocyclic tautomers is brief
