Introduction to the course
  • What is organometallic chemistry
  • Why organometallic chemistry
  • Course objectives and learning outcomes

What is organometallic chemistry?
Chemistry structures, bonding and properties of
molecules. Organometallic chemistry chemistry
of organometallic compounds. organometallic
compounds containing direct metal-carbon bonds.
e. g.
  • Some compounds do not contain metal-carbon bond,
    but they are usually included in the field of
    organometallic chemistry. They include
  • Metal hydride complexes, e.g.
  • Phosphine complexes, e.g.
  • N2-complexes, e.g.
  • Organosilicon and organoboron compounds, e.g.

Exercise. Which of the following compounds is an
organometallic compound?
  • In general, metals in organometallic compounds
  • main group metals
  • transition metals
  • f-block metals. (e.g. Lanthanide Actinide)
  • In this course, transition metals are our main

Lanthanide ???? actinide ??
A brief history of Organometallic Chemistry
1) Organometallic Chemistry has really been
around for millions of years a) Naturally
occurring Cobalimins contain CoC bonds b)
Vitamin B12
  • 2) Zeises Salt synthesized in 1827
    KPt(C2H4)Cl3 H2O
  • Confirmed to have H2CCH2 as a ligand in 1868
  • Structure not fully known until 1975
  • 3) Ni(CO)4 synthesized in 1890
  • 4) Grignard Reagents (XMgR) synthesized about
  • Accidentally produced while trying to make other
  • Utility to Organic Synthesis recognized early on
  • 5) Ferrocene synthesized in 1951
  • a) Modern Organometallic Chemistry begins with
    this discovery
  • b)Many new ligands and reactions produced ever

Common organometallic ligands
Why organometallic chemistry ?
a). From practical point of view OMC
are useful for chemical synthesis, especially
catalytic processes, e.g. gt In production of
fine chemicals gt In production of chemicals in
large-scale gt reactions could not be achieved
Organometallic chemistry is related to
material sciences. e.g. Organometallic
Small organometallic compounds Precursors to
films for coating (MOCVD) (h3-C3H5)2Pd -----gt
Pd film CH3C?C-Au-C?NMe -----gt Au
film Lumminescent materials
  • Biological Science. Organometallic chemistry
    may help us to understand some enzyme-catalyzed

e.g. B12 catalyzed reactions.
b). From academic point of view
Organometallic compounds display many unexpected
behaviors ------gt discover new
chemistry New structures e.g.
New reactions, reagents, catalysts,
e.g. Ziegler-Natta catalyst, Wilkinson
catalyst Reppe reaction, Schwartz's
reagent Sharpless epoxidation, Tebbe's
reagents ..
Nobel -Prize Winners related to the
area -Victor Grignard and Paul Sabatier (1912)
on Grignard reagent -K. Ziegler, G. Natta (1963)
on Zieglar-Natta catalyst -E. O. Fisher, G.
Wilkinson (1973) on sandwich compounds -K. B.
Sharpless, R. Noyori (2001) on hydrogenation and
oxidation -Yves Chauvin, Robert H. Grubbs,
Richard R. Schrock (2005) on metal-catalyzed
alkene metathesis.
Course objectives
To describe the synthesis and general properties
of organometallic compounds. To describe
fundamental organometallic reactions. To
describe catalytic reactions involving
organometallic compounds with a emphasis on
mechanistic understanding.
Learning outcomes
On completion of this unit, you should be able
  • To recognize organometallic ligands and
  • To devise synthetic route to common
    organometallic compounds.
  • Knowledge of fundamental organometallic

    catalytic reactions, including a mechanistic
    understanding and ability to propose catalytic
    cycles for such reactions
