Abstract
The treatment of Z-2-ferrocenylmethylene-, Z-2-arylidene-3-quinuclidin ones and 3-methylene-quinuclidines, as well as E-3-ferrocenylmethylene camphor, -menthone, and -cyclohexanone with NaBPh4 in acetic acid resu lts in their reversible Z-/E-isomerization. The reaction proceeds via hydroxyallyl and crotyl carbocations with a fixed s-cis-conformation. (C) 1998 Elsevier Science S,A. All rights reserved.
