Generation and Reactions of a Benzodehydrotropylium Ion-Co₂(CO)₆ Complex.

ABSTRACT: A series of 7-methylenedehydrobenzo[7]annulen-5-ol hexacarbonyldicobalt complexes were generated by Hosomi-Sakurai reactions of allylsilanes containing o-alkynylarylaldehyde-Co₂(CO)₆ complexes. One of the cyclization products was converted into its corresponding dihydrobenzo[7]annulen-7-ol hexacarbonyldicobalt complex, an immediate precursor to a benzodehydrotropylium-Co₂(CO)₆. The cation was generated in situ and reacted with four nucleophiles, and its aromatic stabilization was determined by computational methods.
