Abstract

The reaction of benzaldehyde pyrazinyl-, pyridazinyl-, and pyrimidinylhydrazones with sodium ethoxide was investigated by means of gas—liquid chromatography (GLC) and mass chromatometry. It was established that the previously discovered new type of cleavage of the N-N bond in pyridylhydrazones under the influence of alkali-metal alkoxides also takes place in a number of azine systems, but the yields of the corresponding N-monoalkylamino derivatives of pyrazine, pyrimidine, and pyridazine differ.
