Instructor:
Dr. R. J. Puddephatt
Office:
Room 100, Chemistry Building
A. Course Outline
1.
Historical introduction to organotransition metal chemistry and catalysis. Qualitative MO theory
for complexes. Electron counting rules.
2.
Metal carbonyls: Structure and bonding, preparations, reactions. Related B-acceptor ligands.
3.
Alkene and alkyne complexes. Structure, bonding, reactivity, role in catalysis.
4.
Carbene, vinylidene and carbyne complexes; applications in synthesis.
5.
More complex unsaturated organic ligands: 0-allyl, 0-cyclopentadienyl, 0-arene etc.
6.
Alkyl and hydride complexes.
7.
Migratory insertion, $-elimination and related reactions; role in catalysis.
8.
Oxidative addition, reductive elimination, bond activation; role in catalysis.
9.
Selected applications in organic synthesis
10.
Industrial homogeneous catalysis: hydrogenation, hydroformylation, hydrosilation, oxidation,
polymerization of alkenes. Acetic acid synthesis and related catalysis. Asymmetric catalysis.
Current challenges.
11.
Heterogeneous and hybrid homogeneous/heterogeneous catalysts.
B. What is expected of the registrant
You are expected to know the concepts and theories used to understand structure, bonding,
mechanism, reactivity and catalysis in organotransition metal chemistry. You are also expected
to know some descriptive chemistry, especially including applications of organotransition metal
complexes in catalysis.
C. Textbooks
There is no prescribed text for the course. Most textbooks of inorganic chemistry contain useful
sections on organometallic chemistry and catalysis. For example:
Inorganic Chemistry, by Shriver, Atkins et al., (Freeman)
Advanced Inorganic Chemistry, by Cotton and Wilkinson et al., Wiley.
There are also several excellent texts on organometallic chemistry and catalysis which are
recommended, including:
Organometallics, by C. Elschenbroich and A. Salzer, VCH.
The Organometallic Chemistry of the Transition Metals, by R.H. Crabtree, Wiley.
Fundamental Transition Metal Organometallic Chemistry, by Lukehart, Brooks-Cole.
Principles and Applications of Organotransition Metal Chemistry, by Collman, Hegedus, Norton and
Finke, University Science Books.
Homogeneous Catalysis, by G.W. Parshall, Wiley, NY.
D. Evaluation
Three in-class tests (15%, 15% and 20%); one final examination (50%). Term tests will be held during the
regular lecture period on January 27, February 15 and March 17. If you miss a term test through illness, the
weighting of marks will be revised appropriately.
There is a three-hour final in the Final Examination period (cumulative, but weighted in favour of the later part
of the course which has not been tested previously).
Course prerequisite: Chemistry 3371f.
Important Announcements:
Scholastic offences are taken seriously and students are directed to read the appropriate policy, specifically,
the definition of what constitutes a Scholastic Offence, at the following Web site:
http://www.uwo.ca/univsec/handbook/appeals/scholastic_discipline_undergrad.pdf
Illness or other serious circumstances
If you are unable to meet a course requirement due to illness or other serious circumstances, you must provide
valid supporting documentation to your instructor (missed assignment deadlines) or the Academic Counselors
in the Dean's office (for a missed midterm/exam) as soon as possible and contact your instructor immediately.
It is the student's responsibility to make alternative arrangements with their instructor once the accommodation
has been approved and the instructor has been informed. In the event of a missed final exam, a
"Recommendation of Special Examination" form must be obtained from the Dean's Office immediately.
For further information please see: http://www.uwo.ca/univsec/handbook/appeals/medical.pdf
A student requiring academic accommodation due to illness, should use the Student Medical Certificate when
visiting an off-campus medical facility or request a Records Release Form (located in the Dean's Office) for
visits to Student Health Services. The Student Medical Certificate form can be found here:
http://www.uwo.ca/univsec/handbook/appeals/medicalform.pdf
Students who are in emotional/mental distress should refer to Mental Health@Western
http://www.uwo.ca/uwocom/mentalhealth/ for a complete list of options about how to obtain help.
For Student Services see: https://studentservices.uwo.ca/secure/index.cfm
Since the policy on medical illness explicitly states that documentation should go to the academic
counselling office and forbids instructors from collecting medical documentation, we are not able to
deal with appeals made on medical grounds at the departmental level. Please follow the Policy
on Accommodation for Illness, and contact the Academic Counselling Office of your home Faculty:
http://www.uwo.ca/univsec/pdf/academic_policies/appeals/accommodation_illness.pdf
Accessibility
Please contact the course instructor if you require material in an alternate format or if any other arrangements
can make this course more accessible to you. You may also wish to contact Services for Students with
Disabilities (SSD) at 661-2111 ext. 82147 if you have questions regarding accommodation.

to catalysis.
•
Sketch and label individual reaction steps that comprise well-known catalytic cycles.
•
Justify observed catalytic performance based on known structure and bonding properties of the
catalyst intermediates.
