Although the reaction of aromatic compounds with allylic chlorides using ZnClz/SiOz gives 2-chloro-I-arylalkanes accompanied with diarylalkanes, similar reaction using ZnC1z/Si02-K2C03/A1z03 produces the monoallylated compound as the major product in good yield. ... Direct allylation of aromatic compounds by electrophilic aromatic substitution reaction is usually very difficult. Re- cently, the use of allylmetal compounds and metal complexes ...
