Acryloyl chloride → HCID 23467942, compound

Participants

Reaction Steps

Into a flask provided with a magnetic stirrer is added 10.0 g of 2-(2H-benzotriazol-2-yl)-4-methylphenol dissolved in 350 ml acetone. Then 10% NaOH is added dropwise until the pH is 9. With stirring, 4.1 g of acryloyl chloride is added dropwise while maintaining the pH between 7 and 9 by addition of dilute base. After the addition is complete, the solvent is evaporated leaving a yellow residue which is dissolved in 80 ml ether and extracted with an equal volume of 5% NaOH solution until the aqueous washings are colorless. After evaporation of the ether, there is left 8.4 g of a yellow residue as the product, whose structure, is confirmed by NMR. The yield is 67.7%.
