Opis ogólny
1,3-Dimethyluracil is a pyrimidine derivative. Stability of the C6-centered carbanions derived from 1,3-dimethyluracil has been investigated in the gas phase and in DMSO and water solutions. The excited state structural dynamics of 1,3-dimethyluracil (DMU) in water and acetonitrile has been studied by resonance Raman spectroscopy. Crystal structure of 1,3-dimethyluracil has been reported. Ultraviolet irradiation of aqueous 1,3-dimethyluracil results in hydration of the 5:6 double bond of the uracil ring to form 1,3-dimethyl-6-oxy-hydrouracil.
Zastosowanie
1,3-Dimethyluracil is suitable reagent used to investigate the steady-state absorption and fluorescence spectra of uracil derivatives. It may be used in the preparation of 2,6-dihydroxynicotinamide.

The stabilities of the C6-centered carbanions derived from 1,3-dimethyluracil, N-methyl-2-pyridone, and N-methyl-4-pyridone were systematically investigated in the gas phase and in DMSO and water solutions. The stabilities of the carbanions in the gas phase and DMSO were directly measured through

The electronic structure of 1,3-dimethyluracil and its dimer is characterized by ab initio calculations. The methylation eliminates the H-bonded isomers and allows one to focus on the pi-stacked manifold. In the neutral species, methylation increases the binding energy by 3-4
