Carbon tetrabromide → 4-(Bromomethyl)benzene-1,2-dicarbonitrile

Participants

Reaction Steps

4-Hydroxymethyl-phthalonitrile from step 2 (1.3 g, 8.2 mmol) was dissolved in THF (41 ml) and treated with Ph3P (3.2 g, 12.3 mmol) followed by CBr4 (4 g, 12.3 mmol). The reaction mixture was stirred at room temp. for 21 hours. The solvent was removed in vacuo and the residue purified by flash chromatography (15% EtOAc/Hexane) to yield the desired product.
