1H and13C nuclear magnetic resonance spectra and X-ray crystal structure of [1-methyl-3-ethyl-(σ-1,3-h2,π-1,2,3-h3)-allyl]nonacarbonyltriruthenium: the allyl group as a five-electron donor

Abstract

The reaction of cis,trans- or trans,trans-hexa-2,4-diene and Ru3(CO)12 is shown, by 1H and 13C n.m.r. spectra and X-ray crystal structure to give a product in which the diene ligand has undergone a skeletal rearrangement producing a π-allyl group, a metal hydride bond, and two metal–carbon σ-bonds.
