A reinvestigation of the fluxionality of tricarbonyl(η6-cyclo-octa-tetraene)-chromium and -tungsten using the carbon-13 Forsén-Hoffman spin-saturation method
Abstract
It is shown that the mechanism of metal migration in [M(CO)3(η6-C8H8)](M = Cr or W) is a combination of 1,2- and 1,3-shifts. The mechanisms of both this migration and also that found for [Cr(CO)3(η6-C8H4Me4-1,3,5,7)] are explained.
