Solvent‐free One‐pot Synthesis of 2,2′‐dithioxo‐[5,5′]bithiazolidinylidene‐4,4′‐diones

Abstract

Solvent‐free one‐pot synthesis of 2,2′‐dithioxo‐[5,5′]bithiazolidinylidene‐4,4′‐dione (birhodanine) derivatives from the reaction of primary amines and carbon disulfide in the presence of dimethyl acetylene dicarboxylate has been reported.

CoFe2O4/Cu(OH)2 magnetic nanocomposite: an efficient and reusable heterogeneous catalyst for one-pot synthesis of β-hydroxy-1,4-disubstituted-1,2,3-triazoles from epoxides

“…[39][40][41][42][43] The reduction of work-up procedures and purication steps, high purity of desired products, short reaction times, high to excellent yields are among the signicant benets of multicomponent one-pot reactions. 44,45 Furthermore, the reaction involving ring opening of epoxides with organic azides in water solvent occurs with perfect regioselectivity and takes advantage of green and benign conditions.…”

Bithiazolidinylidene polymers: synthesis and electronic interactions with transition metal dichalcogenides

“…A one-step synthesis of BT-diones, reported by Nasiri, et al , reacted aliphatic primary amines with carbon disulfide and dimethylacetylene dicarboxylate ( Scheme 1 ). 21 This method produced multi-gram quantities of BT derivatives in one step without the need for chromatographic purification. There are few known functional BT derivatives 22 , 23 and no reports of BT-containing polymers.…”

Copper–birhodanine complex immobilized on Fe3O4 nanoparticles: DFT studies and heterogeneous catalytic applications in the synthesis of propargylamines in aqueous medium

“…Birhodanine derivative was synthesized according to the previously reported method with some modification . Dropwise 3–(triethoxysilyl)propan–1–amine (APTMS) (4 mmol, 0.72 g) was added to a stirred solution of carbon disulfide (4.8 mmol, 0.36 g) and dimethyl acetylene dicarboxylate (DMAD) (2 mmol, 0.28 g) in acetonitrile (4 ml) in 5 min.…”
