3-Chloroaniline → Benzenediazonium, 3-chloro-, tetrafluoroborate(1-) (1:1)

Participants

Reaction Steps

3-Chloroaniline (2.0 g) was dissolved in a solvent mixture of water (30 mL) and concentrated HCl (3.5 mL), and sodium nitrite (1.30 g) was added thereto under ice cooling, followed by stirring for 10 minutes. To the resultant mixture were added concentrated HCl (5.3 mL) and sodium tetrafluoroborate (6.90 g), followed by stirring for 30 minutes under ice cooling. The precipitate was collected by filtration, and was washed with water, methanol, and diethyl ether, to thereby give the title compound (2.63 g). The compound was directly used for the next reaction.
