摘要:
The alkylation of aromatic hydrocarbons with 2-bromo-2-phenyl-gem-dichlorocyclopropane in the presence of catalytic quantities of aluminum chloride was found to afford the corresponding 2-aryl-3-phenyl-1,1-dichloroprop-1-enes. It was shown that the yield of the alkylation products depended on the nature of substituents in the aromatic ring. Compared with the thermal heating, microwave irradiation allows reducing the reaction time and increasing the yield of the corresponding 2-aryl-3-phenyl-1,1-di-chloroprop-1-enes, wherein the ortho-/para-isomers ratio changes.
