1122-10-7, 3,4-Dibromo-1H-pyrrole-2,5-dione is a pyrrolines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Reference Example 17 Preparation of 3,4-Diiodo-pyrrole-2,5-dione To dibromomaleimide (500.0 mg, 2.0 mmol) in acetic acid (50 ml) was added sodium iodide (886.5 mg, 5.9 mmol). The reaction mixture was heated to 120 C. and refluxed for 2 h. The reaction was allowed to cool down to RT, H2O (50 ml) was added and kept at 4 C. for 15 h. The yellow precipitate was filtered off and air dried to afford the desired compound as an orange crystalline powder (415 mg, 60%). 1H NMR (500 MHz, MeOD): no signals; 13C NMR (125 MHz, MeOD): delta=169.3 (C), 119.5 (C); IR (solid, cm-1): 3244 (s), 2944 (m), 2833 (m); MS (EI) m/z, (%): 349 (M, 83), 179 (100); Mass calc. for C4H12O2N: 348.80912. Found: 348.81026. m.p. 238-241 C. (Literature: 254-255 C.).
1122-10-7, The synthetic route of 1122-10-7 has been constantly updated, and we look forward to future research findings.
