O-Toluidine → 2-Methyl-6-pentafluoroethylaniline

Participants

Reaction Steps

To a two-layer system liquid mixture of 10 ml of water and 10 ml of tetrahydrofuran were added 1.07 g (10 mmoles) of 2-toluidine, 2.46 g (10 mmoles) of perfluoroethyl iodide, 1.04 g (10 mmoles) of sodium hydrogen sulfite, 0.65 g (10 mmoles) of zinc and 0.84 g (10 mmoles) of sodium hydrogen carbonate, and the resulting mixture was stirred at room temperature for 3 hours. The organic layer was dried with magnesium sulfate. The gas chromatographic analysis of the organic layer showed that, in terms of area percentage, remaining starting materials were 46%; as for the products, 2-methyl-4-pentafluoroethylaniline was 41% and 2-methyl-6-pentafluoroethylaniline was 8%, the ratio being about 5:1.
