ABSTRACT:
A process for the preparation of vinyl aromatic compounds comprises contacting an aromatic compound and an olefin in the presence of a catalytic amount of a cyclopentadienyl, indenyl, or fluorenyl rhodium complex under reaction conditions sufficient to form the corresponding vinyl aromatic compound. Novel alkyl- or trimethylsilyl-substituted indenyl or fluorenyl compounds are among the compounds suitable for use in the process of the invention.
