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.2682-49-7, name is Thiazolidin-2-one. An updated downstream synthesis route of 2682-49-7 as follows., 2682-49-7
5908-62-3, To a stirred solution of 5-{9-fluoro-6-methanesulfonyl-5-[(S)-oxan-4- yl(phenyl)methyl]-5H-pyrido[3,2-b]indol-3-yl}-4-(2H3)methyl-l-methyl-lH-l,2,3- triazole (40.0 mg, 0.075 mmol) and isothiazolidine 1,1-dioxide (36.1 mg, 0.298 mmol) in NMP (0.40 mL) was added t-BuOK (29.2 mg, 0.261 mmol). This mixture was heated at 65 C for 2 h and cooled to room temperature. The mixture was purified via preparative LC/MS with the following conditions: Column: Waters XBridge Phenyl, 19 x 200 mm, 5- muiotaeta particles; Mobile Phase A: 5:95 ACN: water with 10 mM NH4OAC; Mobile Phase B: 95:5 ACN: water with 10 mM NH4OAC; Gradient: 15-70% B over 20 min, then a 5-min hold at 100% B; Flow: 20 mL/min. Fractions containing the desired product were combined and dried via centrifugal evaporation to give 9.6 mg. (20%).

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 5908-62-3
