Organometallic Chemistry
Course Objectives :
The course aims to develop a vast knowledge about different reactions leading to the formation of various organometallic complexes and the mechanism involved in homo- and heterogeneous catalysis, to make the students learn about the various applications of organometallic complexes in catalysis and to acquaint them with the promising future of organo-transition metal chemistry in industrial, biological and environmental fields.
