Abstract
Kinetic studies on the AgI- and HgII-assisted substitution of co-ordinated carbanions in CoIII corrinoids show that (i) AgI assists the removal of CN– while HgII assists the removal of organo-ligands, (ii) steric hindrance stabilises Et, Prn, and Pri, relative to Me, (iii) steric compression and/or electronic changes destabilise Pri relative to Prn, and (iv) 5,6-dimethylbenzimidazole (bzm) shows a trans-labilising effect relative to H2O.Keywords
