The reaction of veratrole with cinnamoyl chloride and with crotonoyl chloride in the presence of aluminium chloride yielded phenyl vinyl ketones. In the case of cinnamic acid, the preparation of the acid chloride as well as the FRIEDEL-CRAFTS condensation could be carried out in one step, without isolation and purification of the chloride. Application of this procedure to acrylic acid yielded as sole product a β-chloro-ketone derivative, whereas with crotonic acid a mixture of the corresponding phenyl vinyl ketone and β-chloro-ketone was obtained. Again a different result was obtained in the condensation of methacryloyl chloride, which yielded a 1-indanone instead of an acyclic ketone.
