摘要

The bis (imino) pyridine iron dinitrogen compounds,(iPrPDI) Fe (N2) 2 and [(MePDI) Fe (N2)] 2 (μ2-N2)(RPDI= 2, 6-(2, 6-R2-C6H3N CMe) 2C5H3N; 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. ...
