Abstract: Indanes are prepared by reacting substituted or unsubstituted benzyl halides with olefins in the presence of a Lewis acid as catalyst by reacting benzyl halides I I (where R1 and R2=hydrogen, alkyl, alkoxy, cycloalkyl, aryl, aryloxy, aralkyl R3=R1, halogen or an ortho-fused ring system X=halogen) with olefins II II (where R4 to R7=hydrogen or alkyl unbranched at alpha) in the presence of catalytic amounts of titanium tetrachloride.
