Abstract
1501221 Selective alkylation of ortho alkylphenols RHONE-POULENC INDUSTRIES 15 Aug 1975 [16 Aug 1974] 34097/75 Addition to 1402974 Heading C2C A process for preparing an o-alkoxy-p-allylic phenol comprises allylating an ortho-alkoxypara-unsubstituted phenol with an allylic halide, allylic sulphonate or allylic sulphate in the presence of an aqueous solution of (a) an alkali metal hydroxide or an alkaline earth metal hydroxide and (b) an alkali metal salt, acidifying the reaction mixture and recovering the allylated reaction product. In Examples 1-6, guaiacol is reacted with allyl chloride under the reaction conditions of the present process to produce p-eugenol.
