4-Iodobenzenesulfonic acid chloride - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Application | 4-iodobenzenesulfonyl chloride is an aromatic hydrocarbon derivative, which can be used as a pharmaceutical synthesis intermediate. |
| preparation | 4-iodobenzenesulfonyl chloride the preparation is as follows: to be equipped with mechanical stirring, heating Hood, in a dry 5 L three-necked round bottom flask of a water-cooled condenser, the connecting hose of the condenser was charged with 2.5 L of chloroform and chlorosulfonic acid (503g,4.32 mol). The mixture was heated to mild reflux and a solution of iodobenzene (400g; 1.96 mol) in 0.5 L chloroform was added over 1 hour, during which time, the color of the reaction mixture changed from yellow to deep red-purple with the release of HCl. The reaction was heated at reflux for an additional 1 hour. Complete conversion to p-iodobenzenesulfonyl chloride was indicated by GC analysis. The reaction was worked up by pouring the mixture into a 6 L separatory funnel and then discarding the lower layer, which was mostly a mineral acid. The organic layer was neutralized and dried with MgSO 4. Evaporation of the solvent gave 4-iodobenzenesulfonyl chloride as a crude yellow solid; Yield about 593 g (quantitative). If desired, the product can be further purified by distillation under high vacuum. |
