The synthesis and characterisation of the complexes [(p-CH3C6H4NCH(d(OAc)]2 (II) are reported. These complexes react at very different rates with carbon monoxide in methanol to give the ortho-substituted esters, p-CH3C6H4NCHC6H3Y - 2R, R = CO2CH3, with electron withdrawing Y substituents slowing the reaction. The 13C1H} data for II show a linear correlation of δ(C(2)) in the 5′-complexes (Y trans
