Oxonium, trimethyl-, tetrafluoroborate(1-) (1:1) → 4,6-Dichloro-1,2-dimethylquinolinium tetrafluoroborate

Participants

Reaction Steps

The starting material may be prepared as follows. Powered 4,6-dichloro-2-methylquinoline (254 mg.) was added to a stirred solution of trimethyloxonium tetrafluoroborate (177 mg.) in acetontrile (1 ml.), and stirring was continued overnight. The solvent was evaporated and the residue was triturated with ether to give 4,6-dichloro-1,2-dimethylquinolinium tetrafluoroborate (296 mg.). N.m.r. in solvent A:-3.07(s, 3H); 4.44(s, 3H9; 7.9-8.8(complex, 4H).
