This paper describes the use of a catalytic nickel system for the hydrodefluorination of aryl amides. While organofluorine compounds are extremely useful because of their unique properties, there are growing concerns about the impact of these compounds on the environment. Carbon-fluorine bonds are extremely strong, and so getting them to react is a significant challenge for chemists.
This paper describes work from the Milstein group in which ruthenium catalysts with pincer ligands are used to depolymerize nylons by breaking the C-N bond and hydrogenating the resulting products to amines and alcohols. Waste plastic is a serious environmental concern that needs a solution. Organometallic chemists put significant effort into finding ways to convert monomers into polymers, and now we must figure out ways to do the reverse.
Descriptive chemistry of the main group elements with some emphasis on the non-metals. Transition metal compounds: aspects of bonding, spectra, and reactivity; complexes of n-acceptor ligands; organometallic compounds and their role in catalysis; metals in biological systems; preparative, analytical, and instrumental techniques.
From the course catalog: The chemistry of the Main Group elements and the transition metals are studied with emphasis on the properties, structures, and reactivities of these elements and their compounds.
Syllabus for Inorganic Chemistry lecture taught in Spring 2022.
A systematic study of chemical principles as applied to inorganic systems. This class consist of a 3 hour lecture and a 4 hour lab. Special emphasis is placed on group theory and the use of molecular orbital, ligand field, and crystal field theories as tools to understanding the structure and reactivity of inorganic compounds.
The goal of this course is to provide an in-depth introduction to the broad subject of organometallic chemistry. Selected topics include: main group organometallics, oxidation states, ligands, structure and bonding, mechanism and mechanistic analysis, cross coupling, hydrogenation, hydroformylation, olefin polymerization, olefin metathesis, and other applications in homogeneous catalysis and organic synthesis.
This LO is a literature discussion based on one figure in Chan et. al.
This In-Class Activity is meant to follow up discussions of ligand field theory toward the end of MO theory including the effects of sigma donors, pi donors, and pi acceptors, and how it relates to absorption spectra and observed color of some transition metal complexes. Students have learned crystal field theory and the effects of geometry/symmetry on ∆, then we extend to LFT and how the chemistries of different ligands affect ∆.
This 1FLO focuses on the fundamentals of catalysis and the interpretation of catalytic data. The questions guide students through the definition of catalysts, turnover frequency, turnover number, and require the students to extract information from a table of catalytic data. The data set comes from the unprecedented activity of carba-closo-dodecaborate ligated gold catalysts in hydroamination reported by Lavallo and coworkers in 2013 (Lavallo, V.; Wright II, J. H.; Tham, F. S.; Quinlivan, S. Angew. Chem. Int. Ed. 2013, 52, 3172.
