Preparation and Characterization of Some Targeted Complexes of Chromium

The present paper investigates the preparation and characterisation of targeted complexes of Chromium using di-tertiary butyl chromate (TBC) -a Cr(VI) based oxidant, one easily oxidisable and good chelating agent and another ligand -with following aims:

a. Whether Cr in reduced state enters into complexation with the oxidised fragments or with the unreacted substrate(s)?

b. And if yes whether the process is selective as far as the nature of ligands are concerned? What we want to see that if this process can provide a mean to gauze the co-ordinating ‘power’ of the various potential chelating groups present in the system, at least, qualitatively?
