Synthesis of derivatives of 2, 3, 5, 6-tetrachloro |
| Remarks： |
Synthesis of derivatives of 2, 3, 5, 6 - tetrachloro- methylbenzene with electron withdrawing groups was studied. Chlorination could not occur when there were two electron withdrawing groups in the para positions of benzene under designed condition. But if one of them was electron donating group such as methyl, high yield of chlorinated products could be gained in carbon tetrachloride and chlorosulphonic acid at a temperature from 50ºC to 55ºC, and catalyzed by iodine. The products were 2, 3, 5, 6-tetrachloro-4-methylbenzonitrile with yield of 96.3%, 2, 3, 5, 6 - tetrachloro-4- nitrotoluene with yield of 85.5%, 2, 3, 4, 5, 6-pentachloromethylbenzene with yield of 84.2%, and methyl 2, 3, 5, 6-tetrachloro-4-methylbenzoate with yield of 62.1%.
