CY5019 : ORGANOMETALLIC CHEMISTRY

Course Objectives: The learners should be able to analyze the mechanism of selected catalytic organic reactions from the structure-bonding aspects and reactivity of simple organometallic compounds

Learning Outcomes: At the end of the course, the learners should be able to:

Identify the structure and bonding aspects of simple organometallic compounds

Apply different electron counting rules to predict the shape/geometry of low and high nuclearity metal carbonyl clusters

Identify the different types of organometallic reactions and apply the above concepts to explain different catalytic reactions

Course Contents:

Organometallic chemistry of d-block elements: 18-electron rule, concept of hapticity; synthesis, structure and bonding of homo and heteroleptic metal-carbonyls, nitrosyls, alkyls, alkenes, allyl, alkynes, and arenes. Synthesis and reactivity of Fischer and Schrock carbenes.

Infrared spectra of metal carbonyls and olefins.

Neutral spectator ligands: phosphines and N-heterocyclic carbenes.

Metal clusters, Low and high nuclearity clusters, clusters having interstitial atoms, electron counting schemes:

polyhedral skeletal electron pair theory/Mingo’s rule.

Structure and Isolobal analogies.

Metallocenes and bent-metallocenes.

Fluxionality and dynamics in organometallic chemistry

Reactions of organometallic complexes: Substitution, oxidative addition, reductive elimination, insertion and deinsertion.

Catalysis: Organometallic catalysts, Terminology in catalysis: Turnover, turnover number (TON), turnover frequency (TOF). Hydrogenation, Hydroformylation, Monsanto process, Wacker process, Ziegler-Natta polymerization, C-C coupling reactions, Olefin Metathesis and metathesis polymerization
