An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.1122-10-7, name is 3,4-Dibromo-1H-pyrrole-2,5-dione. Here is a downstream synthesis route of the compound 1122-10-7. 1122-10-7
Example 12 Preparation of Di-dansyl-cystamine-maleimide A round bottomed flask was charged with di-dansyl cystamine (100 mg, 0.16 mmol), TCEP (46 mg, 1 eq) and MeOH (10 ml). The reaction mixture was stirred at ambient temperature under argon for 3 hrs. Dibromomaleimide (36 mg, 0.9 eq), in MeOH (5 ml) was then added to the reaction mixture. After 30 mins NaOAc (56 mg, 4 eq), was added to the reaction mixture and the solvent evaporated in vacuo. The residue was worked up with DCM and brine. The organic layers were combined, dried (MgSO4), filtered and concentrated in vacuo. Purification by flash chromatography (silica gel, 0-20% EtOAc-DCM) afforded the desired compound as a yellow gum (40 mg, 40%). 1HNMR (CDCl3, 600 MHz), delta8.5 (2H, d J 8.5 Hz aromatic H’s), delta8.2 (4H, m aromatic H’s), delta7.53 (1H, s CONH), delta7.46 (4H, m, aromatic H’s), delta7.1 (2H, d, J=7.4 Hz aromatic H’s), delta5.65 (2H, t, J 6.27 SO2NH), delta3.3 (4H, t, J 6.0 SCH2), delta3.17 (4H, q, J 6.0 NHCH2), delta2.8 (12H, s NCH3); 13CNMR (CDCl3, 150 MHz), 6165.9, 152.0, 136.5, 134.7, 130.7, 129.94, 129.85, 129.62, 129.57, 128.63, 123.3, 118.8, 115.4, 45.5, 43.6, 31.8; IR (cm-1) 3288 (br) 1720 (s) MS (Na+) m/z relative intensity: 736 (M, 100); Exact mass calculated for [C32H35N5O6NaS4] requires m/z 736.1368. Found 736.1390 (Na+)., 1122-10-7
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 1122-10-7
