Abstract

Allyl derivatives of benzene and its homologues are prepared by heating the hydrocarbon with allyl orthoborate in the presence of a Friedel-Crafts catalyst, particularly ferric chloride, aluminium chloride and boron trifluoride. Preferably 1/25 to 1/50 mol. of catalyst per mol. of hydrocarbon is mixed with the hydrocarbon and the allyl borate is added in small portions over a period of time to a total of about 1/10 mol. per mol. of hydrocarbon, then the mixture is maintained at 50-100 DEG C. for one to two hours, the hydrocarbon layer is separated, washed with water, dried and distilled. The process can be applied to benzene, toluene, xylene, ethylbenzene, propylbenzene, cumene and cymene. In the examples, allylbenzene and p-allylcumene are prepared from benzene and cumene respectively.
