We have become aware of a report by Bergman and co-workers that the abstraction of a
methyl group from [Cp2ZrMe2] with B(C6F5)3 leads to an acceleration of the intramolecular hydroamination reaction of an aminoallene substrate relative to the reaction
in which only [Cp2ZrMe2] is used (L. Ackermann, R. G. Bergman, R. N. Loy, J. Am.
Chem. Soc. 2003, 125, 11 956). We therefore correct our statement on p. 5543 that “alkyl
metallocene cations have been used in organic synthesis, but to the best of our
knowledge not in hydroamination reactions”, with reference to the above-mentioned
publication.
