Abstract
By quantum-chemical method MP2/6-311+G**//B3LYP/6-31+G** competing reaction channels were studied of the formation of pyrazolyl-1,3-oxathiolane and/or bis(2-hydroxyethyl)dithioacetal from 1,3,5-trimethyl-1H-pyrazole-4-carbaldehyde and 2-mercaptoethanol. The kinetically controlled formation of bis(2-hydroxyethyl) dithioacetal is governed by the concentration in the reaction mixture of 2-mercaptoethanol dimers. The reaction by stages of 1,3,5-trimethyl-1H-pyrazole-4-carbaldehyde with the molecules of mercaptoethanol results in the prevailing formation of 2-(pyrazol-4-yl)-1,3-oxathiolane structures.
