Procedure

A mixture of 4-fluorobenzaldehyde (16.4 ml, 0.15 mol), diallylamine (20.8 ml, 0.17 mol), sodium carbonate (18.0 g, 0.17 mol), hexamethylphosphoramide (HMPA) (115 ml), hydroquinone (180 mg) and tetrahexyl ammonium chloride (200 mg) was heated under a nitrogen atmosphere for 100 hours. The reaction mixture was cooled and poured into distilled water (1 L). Extraction with toluene (4×300 ml) followed by washing of the combined extracts with distilled water (3×250 ml), drying over anhydrous magnesium sulfate, filtration and concentration in vacuo yielded 32 g as a viscous yellow oil. Fractional distillation at 0.8 mm Hg gave 15 g (50%) of 4-(N,N'-diallylamino) benzaldehyde as a pale yellow oil.
