Research speed reading in 2021. Recommanded Product: 18331-34-5, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In a document type is Article, and a compound is mentioned, 18331-34-5, 5-Benzylidene-3-ethyl-2-thioxothiazolidin-4-one, introducing its new discovery.
Five new 3-alkyl-5-benzylidene- and five new 3-alkyl-5-cinnamylidene-2-selenorhodanines were obtained by treatment of methylation products of appropriate rhodanines with H2Se. The stability of 2-thiazolinium salts with SCH3 or RNHCH3 group formed during methylation (cf. Scheme 2) is determined by substituents at C-5 and N-3 atoms.
