✦ Synopsis


This paper commemorates the enormous contribution Luigi M. Venanzi made to inorganic coordination chemistry over many years Displacement of norbornadiene (nbd; bicyclo[2.2.1]hepta-2,5-diene) from [Rh(PPh 3 ) 2 (nbd)]ClO 4 by hydrogenation in the presence of PPh 3 and formamide or Me-substituted derivatives, results in the formation of O-bonded formamide complexes [Rh(PPh 3 ) 3 (OCHNH x Me 2Àx )]ClO 4 (x 0, 1, 2) rather than N-bonded derivatives. These have been characterised by spectroscopic measurements and, in the case of [Rh(PPh 3 ) 3 (OCHNHMe)]ClO 4 , by X-ray crystallography. All undergo oxidative addition with H 2 , and the rates of ligand exchange in the Rh I and Rh III complexes have been determined by magnetisation-transfer measurements.
