N-Methylanilinium trifluoroacetate

Tetrahydrofuran was distilled from the ketyl prepared from benzophenone and sodium, but the reaction does not suffer from moisture. Dioxane can also be used, but the iminium salt polymerizes rapidly at the reflux temperature of this solvent (101°C). To avoid polymerization the N-methylanilinium trifluoroacetate should be added in portions to the reaction mixture. [Pg.120]
