Versuchsvorschrift

In a 500-ml round-bottom flask is placed 2.03 g (0.005 mole) of 2,4,6-triphenylpyrylium bisulfate. To this is added 150 ml of ethanol followed by 2.34 g (0.01 mole) of p-decylaniline. This mixture is refluxed for about 8 hours and allowed to cool. A quantity of the starting aniline precipitates and is removed by filtration. The ethanol is then removed to give a yellow waxy material which is washed with ether to give a white powder. This material is then dissolved in acetonitrile to cause the remaining aniline to precipitate. The acetonitrile is removed to give the desired product which is then rinsed with ether to remove any residual acetonitrile. The yield is 1.77 g (0.0028 mole) of 2,4,6-triphenylpyridinium bisulfate as confirmed by nuclear magnetic resonance (1H) and elemental analysis.
