摘要:
Abstract1‐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,6was observed to occur in a remarkable dimer/trimer equilibrium, whereas1forms a dimer. From1and dichlorozirconocene, the 1‐zirconaindane2was obtained, which reacted with B(C6F5)3to form the adduct13. According to spectroscopic data,13is 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 theortho‐fluorine atoms.
