The treatment of Z-2-ferrocenylmethylene-, Z-2-arylidene-3-quinuclidinones and 3-methylene-quinuclidines, as well as E-3-ferrocenylmethylenecamphor, -menthone, and -cyclohexanone with NaBPh4 in acetic acid results in their reversible Z-/E-isomerization. The reaction proceeds via hydroxyallyl and crotyl carbocations with a fixed s-cis-conformation.
