Ethylenediamine → p-Toluenesulfonic acid

Participants

Reaction Steps

A mixture of p-toluenesulfonic acid monohydrate (TsOH) (7.5 mg, 39.4 μmol) and of pentamethylbenzene (6.6 mg, 44.5 μmol, internal standard) in solution in dichloromethane (300 μl) was treated with 3 equivalents of polyimine prepared according to example 1 (12 mg, 120 μmol). After filtering and evaporating, it was observed, by NMR, that the TsOH/pentamethylbenzene ratio was 0.02. Thus, only 0.89 μmol of TsOH remains in the medium, i.e. only 2% of the initial amount.
