摘要

Abstract The mass spectra of 1-substituted 3, 5-dimethyl-1 H-pyrazole-4-carbaldehyde bis (2- hydroxyethyl) dithioacetals and thioacetals were studied for the first time. The main fragmentation pathways of their molecular ions generated under electron impact and chemical ionization were similar. Primary decomposition of the molecular ions of bis (2- hydroxyethyl) dithioacetals involves elimination of 2-sulfanylethanol molecule with ...
