Abstract

Abstract Thioacetalization of the nitrobenzaldehydes with 2-mercaptoethanol is easily carried out in the presence of TMSCl and dichlorodimethylsilane without heating and using of additional solvent. The reaction direction is defined by the reagents ratio and led to formation of bis (2-hydroxyethyl) dithioacetals (yield 76-91%) or 1, 3-oxathiolanes (yield 76- 91%). Bis (2-hydroxyethyl) dithioacetals are easily transformed in the corresponding 1, 3- ...
