Abstract
In this study, a one-pot reaction between β-keto esters or dialkyl acetylenedicarboxylates with hydrazines, carbon disulfide, and dialkyl acetylenedicarboxylates in the presence of triethylamine is reported. This reaction proceeded at room temperature and was completed within 6 h to produce functionalized pyrazolone-1,4-dithiafulvene hybrids in good yields.
