Inorganic Chemistry

Submitted by Gary Guillet / Furman University on Thu, 04/25/2019 - 16:02
Description

Introduces students to a broad overview of modern inorganic chemistry. Included are considerations of molecular symmetry and group theory, bonding and molecular orbital theory, structures and reactivities of coordination compounds, organometallic chemistry, catalysis and transition metal clusters. Laboratory experiences will include the measurement of several important features of coordination compounds, such as their electronic spectra and paramagnetism, as well as the synthesis and characterization of organometallic compounds.

Redox-switch polymerization catalysis

Submitted by Chip Nataro / Lafayette College on Tue, 03/26/2019 - 13:49
Description

This is the full literature discussion based on a communicaiton (J. Am. Chem. Soc. 2011, 133, 9278). This paper describes a redox-switch yttrium catalyst that is an active catalyst for the polymerization of L-lactide in the reduced form and inactive in the oxidized form. The catalyst contains a ferrocene-based ligand that serves as the redox active site in the catalyst. This full literature discussion is an extension of the one figure literature discussion that is listed below.

1FLO: Redox-switch polymerization catalysis

Submitted by Chip Nataro / Lafayette College on Fri, 03/22/2019 - 16:11
Description

This is what I hope will be a new classification of learning object called a one figure learning object (1FLO). The purpose is to take a single figure from a paper and present students with a series of questions related to interpreting the figure. This literature discussion is based on a paper (J. Am. Chem. Soc. 2011, 133, 9278) from Paula Diaconescu's lab in which a yttrium polymerization catalyst with a ferrocene-based ligand can effectively be rendered active or inactive depeneding on the valence state of the ligand.

Supramolecular Chemistry Videos

Submitted by Shirley Lin / United States Naval Academy on Sun, 03/03/2019 - 08:08
Description

The Rebek Laboratory homepage contains information on and molecular visualizations of a variety of host-guest systems developed by the research group over several decades. The theme behind this set of examples is the use of hydrogen-bonding to achieve self-assembly. Under the "Research" tab, one can find four videos with narration: an introduction to molecular assembly and three videos of specific examples of self-assembled host systems (the cavitand, the cylinder and the volleyball).

Advanced ChemDraw (2019 Community Challenge #2)

Submitted by Chantal Stieber / Cal Poly Pomona on Tue, 02/12/2019 - 12:12
Description

This in-class activity was designed for a Chemical Communications course with second-year students. It is the second part of a two-week segment in which students learn how to use ChemDraw (or similar drawing software to create digital drawings of molecules).

More Electron Counting and CBC Assignments for Organometallic Complexes

Submitted by Matt Whited / Carleton College on Thu, 01/31/2019 - 14:55
Description

This in-class group activity extends my original post by providing more examples of varying difficulty for students to assign MLXZ classifications and electron counts to organometallic complexes.  The answers to these are unambiguous within the CBC system, but they provide excellent starting points for conversation with students about bonding formalisms with organometallics.

Inorganic Chemistry

Submitted by James F. Dunne / Central College on Tue, 01/29/2019 - 16:16
Description

This course is an introduction to the field of inorganic chemistry.  The student is expected to be well-versed in the material covered in general chemistry, as this will serve as the foundation and launching point for the material to be covered this semester. The course will begin by examining the properties of the elements, and expand outward to consider chemical bonding and the electronic factors that govern metal reactivity.  These factors include acid-base theory, thermodynamics, electrochemistry and redox, and coordination chemistry.

Guided Literature Discussion of “Next-Generation Water-Soluble Homogeneous Catalysts for Conversion of Glycerol to Lactic Acid”

Submitted by M. Watzky / University of Northern Colorado on Mon, 01/28/2019 - 14:50
Description

This Guided Literature Discussion was assigned as a course project, and is the result of work originated by students Joie Games and Benjamin Melzer.  It is based on the article “Next-Generation Water-Soluble Homogeneous Catalysts for Conversion of Glycerol to Lactic Acid” by Matthew Finn, J. August Ridenour, Jacob Heltzel, Christopher Cahill, and Adelina Voutchkova-Kostal in Organometallics 2018 37 (9), 1400-1409.
