Application

2-Pyrimidinethiol has been used to study the highly selective palladium catalyzed kinetic resolutions of the racemic cyclic allylic carbonates and racemic acyclic allylic carbonates. It has also been used to study the photodegradation of 2-pyrimidinethiol in aerated aqueous solution using zinc oxide.

The molecular vibrations of 2-mercapto pyrimidine (MP) and 2,4-diamino-6-hydroxy-5-nitroso pyrimidine (DAHNP) were investigated in polycrystalline sample, at room temperature, by Fourier transform infrared (FT-IR) and FT-Raman spectroscopics. In parallel, ab initio and various density functional (DFT) methods were used to
