Abstract
The bis(imino)pyridine iron dinitrogen compounds, (iPrPDI) Fe(N2)2 and [(MePDI)Fe(N2)] 2(μ2-N2) (RPDI = 2,6-(2,6-R 2-C6H3N=CMe)2C5H 3N; R = iPr, Me), promote the catalytic intermolecular [2π + 2π] cycloaddition of ethylene and butadiene to form vinylcyclobutane. Stoichiometric experiments resulted in isolation of a catalytically competent iron metallocycle intermediate, which was shown to undergo diene-induced C-C reductive elimination. Deuterium labeling experiments establish competitive cyclometalation of the bis(imino)pyridine aryl substituents during catalytic turnover.
