Insertion of isocyanide into the uranium–carbon σ-bond of triscyclopentadienyl(methyl)uranium(IV): spectroscopic and structural characterization of the resulting η2-N-cyclohexyliminoethyl complex

Abstract

U(cp)₃Me(cp =η⁵-cyclopentadienyl) reacts at room temperature with CNC₆H₁₁ to give quantitatively the insertion product U(cp)₃[η²-CmeN(C₆H₁₁)], the ¹H n.m.r. data and the X-ray crystal structure of which show that the imine ligand is η²-co-ordinated; the cyclohexyl group is equatorially substituted by the N atom and experiences notable steric congestion.
