A balanced equation for a chemical reaction indicates what is reacting and what is produced, but it reveals nothing about how the reaction actually takes place. The reaction mechanism is the process, or pathway, by which a reaction occurs.5908-62-3, name is 1,1-Dioxo-isothiazolidine. An updated downstream synthesis route of 5908-62-3 as follows., 5908-62-3

General procedure: General procedure for synthesis of N-substituted-rhodanine derivatives RhAs: To a solution of aldehydes (3a-3h, 1.0 equiv.) in ethanol (10 mL) was added slowly to the solution of 3-amino-2-thioxothiazolidin-4-one (2, 1.0 equiv.) in EtOH. The reaction mixture was stirred at room temperature without a catalyst for between 4 h and 12 h, and was monitored by TLC. After, the mixture product was recrystallized from EtOH. After recrystallization, N-substituted-rhodanine derivatives (RhAs) were obtained as follows.

There are, however, a few established termolecular elementary reactions. The reaction of nitric oxide with oxygen appears to involve termolecular steps. you can also browse my other articles about 3-Aminorhodanine
