COURSE DESCRIPTION/OBJECTIVES:
CH 611 is an advanced inorganic graduate course with a focus on transition metal organometallic chemistry (prerequisite CH 370 or equivalent). As an active participant in this course you will learn about the structural and electronic properties of transition metal organometallic complexes as well as their catalytic applications.
It is recommended to bring a copy of lecture notes to class in addition to a periodic table and a good sense of learning and curiosity!!
Further discussion and active participation is encouraged during the lecture.
SYLLABUS
Lectures will be uploaded on a weekly basis.
Lecture 1: Atomic Structure and Periodicity (09/09/09)
extra reading: the periodic system of the elements
Lecture 2: The Transition Metals (09/14/09)
extra reading: determination of electronegativities
Lecture 3: The Transition Metals II (electron counting) (09/16/09)
extra reading: valency, oxidation state and formal charge
extra material: Common ligands and ions ...work in progress
Lecture 4: Sigma bonding (09/21/09)
Quiz # 1: electron counting (key)
Lecture 5: Pi bonding (09/23/09)
Literature analysis: CO Photodissociation in Cr(CO)6 ....will discuss this paper after our workshop on MO corellation diagrams!!
Lecture 6: MO corellation diagrams (09/28/09)
Symmetry and Point Group revision
Lecture 7: Sigma bound ligands (09/30/09)
Literature analysis: agostic bonding .....take some time to revise electron counting
(remember an agostic H does not donate 2 electrons to a metal like a traditional Hydride. Only following B-elimination, i.e. when C-H bond is broken, its two
electrons are donated to the metal via the Hydride ligand)
Lecture 8: Metal Hydrides, Dihydrogen Complexes and Agostic Interactions (10/05/09)
Quiz # 2 : Ligand field theory (key)
Lecture 9: Sigma Donor / Pi Acceptor Ligands (10/07/09)
Exam 1 key (10/14/09)
Lecture 10: Fischer Carbene Complexes (10/19/09)
Literature analysis: Electronic Structure of Alkoxychromium(0) Carbene Complexes
Lecture 11: Schrock Carbenes; Fischer & Schrock Carbynes (10/21/09)
Lecture 12: NHC Carbenes and Metathesis (10/26/09)
Quiz # 3: Fischer and Schrock Carbenes (key)
Lecture 13: Pi Bonding (alkenyl, alkynyl) Ligands # 1 (10/28/09)
Lecture 14: Pi Bonding (allyl,dienes,Cp) Ligands # 2 (11/02/09)
Lecture 15: Literature discussion: Charge Delocalization & slides (11/04/09)
Further reading: Intervalence Transitions 1 & 2 & 3

Lecture 19: Electrophilic/Nucleophilic Addition & Subtraction (11/25/09)
Lecture 20: Organometallic Catalysis I (11/30/09)
Lecture 21: Organometallic Catalysis II + Quiz (12/02/09)
Lecture 22: Literature Presentations (12/07/09)
Lecture 23: Literature Presentations (12/09/09)
Lecture 24: Final review (12/14/09)
FINAL EXAM (12/16/09)
In the final weeks of the course students are required to give an oral presentation (30 min including discussion - 100 points)
Presentation topics will be decided 3-4 weeks in advance based on current literature. In the week prior to their presentation the student must submit an abstract (1 page max.) which should include the presenting authors name, a presentation title, a brief outline of the topic(s) to be discussed and relevant literature references. The grade will be assigned based on the abstract (20 points), the scientific content of the presentation (30 points - including introduction to discussion topic), the ability to convey topic of presentation (20 points) and the students understanding of the topic (30 points - including ability to answer questions….within reason of course!).
EXAMS
five 20 minute quizzes (20 points each)
two 1.5 hour in-class exams (200 points each)
one 3 hour final exam (300 points)
Final Exam will be held on wednesday Dec 16th from 5.30 - 8.30 pm.
