Linkage isomerization in β-diketonates resulting from sterically induced intramolecular rearrangement in metal-ligand bonding have been observed during phenyl isocyanation of β-diketonato and β-ketonimino complexes of chromium(III), cobalt(III), cobalt(II), nickel(II) and copper(II). Steric repulsions operating between γ-CO·NH·Ph and α-C6H5 or between γ-CO·NX·Ph (γ-halogenated substrate) and α-CH3/C6H5
