The Evolution of Fe‐catalyzed Nucleophilic Activation of Acceptor‐substituted Vinyl‐ and Arylcyclopropanes

Abstract

AbstractAcceptor‐substituted vinyl‐ (VCP) and arylcyclopropanes (ACP) are reactive substrates for nucleophilic activation using Bu4N[Fe(CO)3(NO)] (TBA[Fe]). In this account, the application of this catalytic strategy in traceless allylic substitution, [3+2]‐cycloaddition, and Cloke‐Wilson rearrangement will be presented. Additional information, derived from detailed spectroscopic and theoretical investigations, is discussed. These results not only lead to a deeper understanding of the reactivity of the catalyst in VCP and ACP activation, but also set the stage for a new type of catalyst activation using photochemical irradiation at 415 nm.
