Participants
| Role | Name | HCID | Charge |
|---|
| Reactant | p-Toluenesulfonic acid monohydrate | HCID 521998 | — |
| Reactant | 1,1-Dichloro-N,N,N',N'-tetramethylmethanediamine | HCID 12544745 | — |
| Product | HCID 178483688 | HCID 178483688 | 97.8% |
Reaction Steps
3.0 g (17.5 mmol) of bis(dimethylamino)dichloromethane and 3.33 g (17.5 mmol) of p-toluenesulfonic acid monohydrate are mixed. The mixture is heated to 100° C. over the course of 30 min, and a vacuum of 7 Pa is subsequently applied over one hour. Cooling to room temperature gives 5.25 g of bis(dimethylamino)chlorocarbenium tosylate, corresponding to a yield of 97.8%.
