26364-65-8, Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.26364-65-8, name is 2-Cyanoimino-1,3-thiazolidine, below Introduce a new synthetic route.
General procedure: A solution in absolute ethanol (30 mL/mmol) of the adequate aldehyde (1 equiv) and hydrazine (1 equiv) was heated under reflux for 5-18 h depending on the reactants. After cooling to room temperature, the precipitated solid was collected by filtration and dried under vacuum to afford the corresponding hydrazone. If no precipitate was observed, the reaction mixture was concentrated under reduced pressure. 4.2.25 (E)-4-(2-(4-Hydroxy-3-methoxybenzylidene)hydrazinyl)-5-thioxodihydrothiophen-3(2H)-one (4g). 30 Yellow solid, yield: 37%, mp: 161.5-163.5 C.
