Facile synthesis of new (Z)-6-arylmethylidene-1,3,4-thiadiazin-5(6H)-one derivatives
摘要:
3-Aryl-2-sulfanylpropenoic acids reacted with acetohydrazonyl chlorides in refluxing absolute ethanol in the presence of equimolar amounts of triethylamine, forming (Z)-6-arylmethylidene-1,3,4-thiadiazin-5-one derivatives. X-ray study on the crystal of one of the obtained products was carried out.
