Organometallic Chemistry and Spectroscopy

Types of transition metal to carbon bonds. Classification of organometallic compounds 

(on the basis of hapticity and polarity of M-C bond).  Nomenclature and general characteristics, valence electron count (16 and 18  electron rules).

Routes of synthesis for s-alkyls and aryls of transition metals, stability of organometallic

            compounds and decomposition  pathways.  Preparation,  structure and bonding of carbene and carbyne complexes (both Fischer and Schrock types).

Preparation, properties, structure and bonding of h⁵- dienyl  complexes, h⁶- arene & triene complexes (nucleophilic and electrophilic substitution), fluxionality and dynamic equilibria in h²- olefin,  h³- allyl  and  h^5-dienyl complexes.

Principles and important reactions of transition metal organometallics: Oxidative    addition, insertion and product isolation (reductive elimination and β- elimination).

Homogeneous catalysis: Hydrogenation of alkenes, hydrosilylation of alkenes, metathesis of alkenes, oligomerization and polymerization of alkenes and alkynes, hydroformylation of alkenes, acetic acid synthesis and other carbonylation reactions, oxidation reactions of alkenes.

Heterogeneous catalysis: Fischer Tropsch process- Methanation reaction, synthesis of      methanol, gasoline production, water gas shift reaction, role of ZnO/Cr₂O₃ in the reaction, acetic acid synthesis.

Metal carbonyls: Preparation, properties, structure and bonding with special reference to    dinuclear and polynuclear carbonyls . Vibrational spectra of metal carbonyls (bridging and terminal) for structural elucidation
