4-Methylbenzenesulfonyl azide - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | p-Toluenesulfonyl azide a chemical intermediate with a wide range of uses. For the preparation of a copper surface corrosion inhibitor assembly film, synthesis of α-diazoester compounds, for the preparation of 4-amino imine coumarin derivatives, for the preparation of 3-hydroxyimidazo [1,2-a] pyridine derivatives. |
| Application | One of the uses of p-Toluenesulfonyl azide (TsN3) in organic chemistry is as a transfer reagent for azide functional groups. The reagent can introduce a diazonium functional group at an active methylene position, and react with an olefin to form a hetero-tricyclic compound. |
| preparation | at room temperature, 13.8g of p-Toluenesulfonyl chloride (73mmol) was sequentially added to a ml flask, 50ml of water and 5.7g of sodium azide (87mmol) were stirred for 2 hours. The reaction was monitored by TLC until the reaction was complete, concentration gave 12.7g of the product P-Toluenesulfonyl azide in a yield of 88%. |
