In the aluminum chloride-nitromethane system 2-methyl-3-p-X-phenyl-2-butenes (X = H, CH3, OCH3) form 1,1,4-trimethyl-4-isopropyl-7-X-2-p-X-phenyl-1,2,3,4-tetrahydronaphthalenes.The reaction is a multistage process including isomerization of the initial alkene to the terminal alkene, codimerization of these two unsaturated compounds, a 1,2-hydride shift in the dimeric intermediate, and intramolecular cycloalkylation of the aromatic ring.
