| Abstract: | Displacement of norbornadiene (nbd; bicyclo2.2.1]hepta‐2,5‐diene) from Rh(PPh3)2(nbd)]ClO4 by hydrogenation in the presence of PPh3 and formamide or Me‐substituted derivatives, results in the formation of O‐bonded formamide complexes Rh(PPh3)3(OCHNHxMe2−x)]ClO4 (x=0, 1, 2) rather than N‐bonded derivatives. These have been characterised by spectroscopic measurements and, in the case of Rh(PPh3)3(OCHNHMe)]ClO4, by X‐ray crystallography. All undergo oxidative addition with H2, and the rates of ligand exchange in the RhI and RhIII complexes have been determined by magnetisation‐transfer measurements. |
