Reaction Steps

2-Cyano-4-(thiocyanato)benzenediazonium fluoroborate (2.98 g (10.9 mmol)) was decomposed by first heating with a heat-gun until until the whole mass became black and then by heating to 200° C. in an oil bath for 30 minutes. After cooling, water was added and the resulting mixture was extracted with ethyl acetate. The extract was washed with a saturated aqueous solution of sodium chloride, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was then distilled by means of a glass tube oven under reduced pressure, and a fraction which boiled at 180-240 ° C./0.2 mmHg was collected to give 0.29 g (15%) of 2-fluoro-5-(thiocyanato)benzonitrile as a pale yellow-white crystals.
