The alkylation of benzene, toluene, and ethyl- and isopropylbenzenes with allyl bromide in the presence of FeCl3.2.5H2O, FeBr3.3.5H2O, ZnCl2/Al2O3, and ZnBr2/Al2O3 is fairly selective and leads mainly to the formation of 1-aryl-2-bromopropanes with yields of 54-80percent.

The dithiane 11 is alkylated with prenyl bromide to give 12.Hydrogenolysis of 12 with Raney-Nickel yields α-curcumene (6), hydrolysis of 12 gives the ketone 13.Prenal dithiane (14) is alkylated with 8 to give 15. ar-Turmerone (16) is formed by hydrolysis of 15.Reaction of 15 with sodium in liquid ammonia leads to a mixture of α-curcumene (6) and β-curcumene (10).
