37. Note added in proof (November 25, 1997): Shapiro and co-workers have very recently reported a more detailed account of the syntheses of compounds closely related to 15. This work represents a significant advance in methodology towards viable bridge-type zwitterions: D. S. Stelck, P. J. Shapiro, N. Basickes, A. L. Rheingold, Organometallics 1997, 16, 4565.
