Course catalog description: The chemistry of non-metals. This course consists of a systematic study of the properties and reactions of the elements and their compounds based upon modern theories of the chemical bond, as well as from the viewpoint of atomic structure and the periodic law.
Inorganic chemistry interfaces and overlaps with the other areas of chemistry. Inorganic chemists synthesize molecules of academic and commercial interest, measure properties such as magnetism and unpaired electron spin with sophisticated instruments, study metal ion uptake in living cells, and prepare new materials like photovoltaics. Inorganic chemistry is a diverse field, and we will only be able to touch on some of the chemistry of the 118 elements that currently reside in the periodic table.
During our first fellows workshop, the first cohort of VIPEr fellows pulled together learning objects that they've used and liked or want to try the next time they teach their inorganic courses.
This course uses molecular orbital theory to explain the electronic structure and reactivity of inorganic complexes. Topics include symmetry and its applications to bonding and spectroscopy, electronic spectroscopy of transition-metal complexes, mechanisms of substitution and redox processes, organometallic and multinuclear NMR.
I do not require a formal text but George Stanley's organometallic chemistry 'book' on VIPEr is made available to students (the link is found below).
This problem set was designed to be an in-class activity for students to practice applying their knowledge of metal-metal bonding (as discussed in the previous lecture) to recently published complexes in the literature. In this activity, complexes from four papers by Christine M. Thomas and coworkers are examined to give students practice in electron counting (CBC method), drawing molecular orbitals, and fundamental organometallic reactions.
This literature discussion is based on a paper by Bill Jones and Frank Feher (J. Am. Chem. Soc., 1986, 108, 4814-4819). In this paper, they study the activation of aromatic C-H bonds by a rhodium complex. Through careful experimental design, they were able to examine isotope effects on the selectivity of the reaction. Analysis of the rate data allowed them to prepare a reaction coordinate free energy diagram. This paper also introduces the effects of C-H bond breaking in early or late transition states on the vibrational energy spacing at both ground and excited states.
This literature discussion is based on a paper by Karen Goldberg (J. Am. Chem. Soc., 1995, 117, 6889-6896). In this early paper by Goldberg, she studied the reductive elimination of ethane and methyl iodide from dppePtMe3I. The paper is well written, and approachable for undergraduates. It shows a real, interesting application of thermodynamic and kinetic methods to the study of a problem in mechanistic chemistry.
