Abstract
SUMMARY
Title: Studies on the catalytic properties of some transition metal complexes.
The thesis comprises of five chapters:
Chapter 1 includes the introduction and a literature survey on the azo compounds
and their complexes.
Chapter 2 concerned with the experimental work. The following ligands
