    • In this paper, "alkyl/hydride" exchange refers to an alkyl transfer from the metal to boron with concomitant transfer of hydride from boron to the metal. The term "hydride/alkyl" exchange, on the other hand, refers to the reverse process, i.e., alkyl from boron to metal and hydride from metal to boron.

    • note
    • Addition of a small amount of THF to benzene solutions of 4 results in formation of an adduct in which the phenyl resonances for the benzylidene moiety return to a "normal" pattern. Although we have not fully characterized 4·THF, it is apparent that the THF donor is able to displace the multihapto benzylidene ligand.
