1‐Mercuraindane ( 6 ) was prepared in three steps from 1‐bromo‐2‐(2‐bromoethyl)benzene ( 3 ) and converted into 1‐magnesaindane ( 1 ) by reaction with magnesium. In solution, 6 was observed to occur in a remarkable dimer/trimer equilibrium, whereas 1 forms a dimer. From 1 and dichlorozirconocene, the 1‐zirconaindane 2 was obtained, which reacted with B(C 6 F 5 ) 3 to form the adduct 13 . According to spectroscopic data, 13 is formed by attack of the β‐methylene carbon atom at the boron atom and has a zwitterionic structure with weak interactions between the zirconium ion and one of the ortho ‐fluorine atoms.
