The 1 H NMR spectra of various alkyl substituted η 3 ‐allyl transition metal complexes (MNi, Ru) have been analysed. The chemical shifts of the η 3 ‐allyl protons can be calculated using additive increments; the values of the syn and anti vicinal proton‐proton coupling constants approach each other on alkyl substitution of the η 3 ‐allyl group.
