| | Tosyl azide Usage And Synthesis |
| Description | Tosyl azide is a reagent used in organic synthesis. It is prepared by the reaction of tosyl chloride with sodium azide in aqueous acetone.
| | Applications | Tosyl azide is utilized for the introduction of diazo and azide functional groups. Moreover, it is used as a nitrene and a substrate for [3+2] cycloaddition reactions.
| | Safety | Tosyl azide is a very volatile chemical that should be carefully stored and handled.
| | Chemical Properties | Colorless to slight yellow liquid | | Uses | Used for the introduction of azide and diazo functional groups. It is also used as a nitrene source and as a substrate for [3+2] cycloaddition reactions. | | Uses | 4-Methylbenzenesulfonyl Azide can be used to target Bcl-2 family proteins to potentially treat cancer. | | Uses | p-Toluenesulfonyl azide solution can be employed as a reagent along with alkyne, and amine in the three-component coupling reaction for the synthesis of N-sulfonylamidines in presence of copper catalyst.
It can also be used in the synthesis of N-sulfonyl-1,2,3-triazoles by azide-alkyne cycloaddition reaction in the presence of copper catalyst. | | Synthesis Reference(s) | Synthetic Communications, 17, p. 1015, 1987 DOI: 10.1080/00397918708063962
