A proof of the validity of the application of Woodward–Hoffmann rules to the fluxionality of Fe(η4-C8H8)(CO)2(CNPri)
Abstract
Magnetisation transfer measurements have been applied to the 13C n.m.r. spectrum of Fe(η4-C8H8)(CO)2(CNPri) to demonstrate specific transfer, completely consistent with the Woodward–Hoffmann mechanism, but inconsistent with the least motion mechanism.
