Neighbouring group participation reactions in nitrile- and amido-N-bonded pentaamminecobalt(III) complexes in which the unique ligand contains a remote amide group

Abstract

The [(NH3)5CoNCCH2CONH2]3+ ion hydrates in aqueous base to form [(NH3)5CoNHCOCH2CONH2] 2+ (33%) and a cobalt(II) species. The kinetics have been measured: kobsd=((kOH+Kke-)[OH-])/(1+K[OH -]) where K=7.9×103 (pKa=9.9), kOH=50 M-1 s-1 and ke-=1.4×10-2s-1. Show more
