Abstract
The complexes [{M(C5Me5)}2(OH)3]OH (1, M = Rh; 2, M = Ir) react with aniline in the presence of PF6 – or BF4 – to give the µ-anilido-complexes [{M(C5Me5)}2(µ-NHPh)(µ-OH)2]+. Models show that the anilido-ligand sits rigidly in a pocket between the metal atoms and the n.m.r. spectra indicate there to be no rotation about the C–N bond. Primary alkylamines react with (1) to give tris(amine) complexes [Rh(C5Me5)(NH2R)3]2+(R = n-propyl or benzyl) which immediately dissociate in solution. Reasons for the differences in behaviour of the two types of amines are discussed.Keywords
