The regioselectivity of reaction of tricarbonyl(1,1-dimethylindane)chromium with selected electrophiles and nucleophiles has been shown to be influenced by the preferred conformation of the tricarbonylchromium group.Nucleophiles preferentially react at carbon atoms eclipsed by a chromium-carbonyl bond and electrophiles at carbon atoms in staggered positions.When similar reactions were attempted with some chelated arenechromium dicarbonyl phosphorus compounds only low yields of substitution products were obtained.

4-tert-Butyl-1,1-dimethylindan was synthesized to help establish the identity of products (5- and 6-tert-butyl-1,1-dimethylindan as minor and major products, respectively) from the sulfuric acid catalyzed condensation of tert-butylbenzene and isoprene.NMR (1H and 13C) studies of these hydrocarbons and their corresponding indanones, obtained through chromic acid oxidation, provided structural proof.Gated decoupling experiments were crucial to complete assignment.
