Pyrazine chemistry. Part 9. Oxygenation of pyrazines and pyrimidines
Journal of the Chemical Society, Perkin Transactions 1, 1979Singlet oxygen adds to certain substituted pyrazines and pyrimidines to form the endo-peroxides in high yield. The peroxides derived from the pyrazines are often stable compounds. 2,5-Diethoxy-3,6-dimethyl-3,6-epidioxy-3,6-dihydropyrazine can be reduced to the corresponding diol with sodium borohydride, whilst the parent pyrazine is regenerated by ...

Vapour and crystal spectra in polarized light of pyrazine-d0, cis pyrazine-d2 and pyrazine-d4
Spectrochimica Acta, 1964Abstract The infrared spectra of pyrazine-d0, cis pyrazine-d2 and pyrazine-d4 have been measured between 4000 and 400 cm−1. The spectra have been obtained in the vapour and solid states. The dichroic behaviour of the bands has been measured on polycrystalline fully oriented samples.
