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 6h to produce functionalized pyrazolone-1,4-dithiafulvene hybrids in good yields.
