An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.5908-62-3, name is 1,1-Dioxo-isothiazolidine. Here is a downstream synthesis route of the compound 5908-62-3. 5908-62-3

General procedure: To a mixture of tetrazoloquinoline aldehyde 1a (1 mmol) and rhodanine 2a (1 mmol), 20 mol % [HDBU][HSO4] was added, and the mixture was heated on an oil bath at 80 C for 30 min. During the reaction process, the mixture was solidified and after completion of the reaction (monitored by TLC), the reaction was cooled to room temperature, water was added and stirred for 5 min. The solid obtained was removed by filtration and recrystallized from EtOH-DMF. The filtrate was dried under reduced pressure to recover ionic liquid and reused in subsequent cycles.
