| DICHLORAMINE T Usage And Synthesis |
| Uses | Germicide. | | Uses | N,N-Dichloro-p-toluenesulfonamide (TsNCl2) can be used as:???????? - A nitrogen source for the preparation of aziridines from electron-deficient α,β-unsaturated alkenes in the presence of palladium catalyst.??????
- A reagent in the synthesis of dichlorohaloamines by aminohalogenation of functionalized olefins using copper(I) chloride or 4-dimethylaminopyridine (DMAP) catalyst.???????
- A chlorinating agent in the regioselective synthesis of α-mono chlorosulfoxides from dialkyl sulfoxides or alkyl aryl sulfoxides.
| | Purification Methods | Crystallise it from pet ether (b 60-80o) or CHCl3/pet ether. Dry it in air <55o and store in the dark. It is soluble in CHCl3 (~1:1), *C6H6 (~1:1) and CCl4 (~1:2.5). It is a germicide and antibacterial as it readily liberates chlorine, and it should not smell strongly of chlorine; otherwise it should be purified. Alternatively dissolve ~15g of reagent in 75mL of hot acetic acid and precipitate it by addition of 37mL of N/10 bleaching powder solution (NaOCl), filter off, wash it with a dilute solution of the latter, dry as above (m 78-84o) and recrystallise it. “Sharp drying” will decompose it.
