Acetonitrile → 4-(Biphenyl-2-yloxy)-3,5,6-trichlorophthalonitrile

Participants

Reaction Steps

3,4,5,6-tetrachlorophthalonitrile (5 g), 2-phenylphenol (3.201 g), K2CO3 (3.898 g) and acetonitrile (50 ml) are put in a 100 ml flask and then heated and refluxed. When the reaction is complete, the resultant is filtered with tetrahydrofuran (THF) to obtain a solid, the solid is added to a small amount of dichloromethane and dissolved therein, and hexane is added thereto, obtaining a crystallized solid (4-(biphenyl-2-yloxy)-3,5,6-trichlorophthalonitrile). Herein, the obtained solid is washed several times, filtered and vacuum-dried.
