Six-coordinate Carbon In-class Activity

Submitted by Kyle Grice / DePaul University on Fri, 02/03/2017 - 22:29
Description

This is an in-class exercise developed based on a recent paper in Angewandte Chemie International Edition that reported a crystal structure of "six-coordinate" carbon. We normally think of carbon being four-coordinate at most, but this case has definitive evidence otherwise. However, we can use our inorganic chemistry knowledge to understand the structure and bonding of this molecule and rationalize its stability. Students do a pre-class exercise and then construct the MO of fhe molecule in class together.

Reactivity of a platinum benzyne compound

Submitted by Chip Nataro / Lafayette College on Mon, 01/23/2017 - 14:02
Description

The literature discussion is based on a paper by Gagné (Organometallics 2015, 34, 2707).  In this work, the in situ generation of benzyne is examined. The benzyne coordinates to a platinum center with a tridentate (pincer) phosphine ligand and a methyl group. This provides an opportunity to discuss the characterization of compounds that have NMR active nuclei that are not 100% naturally abundant. Protonation of the benzyne compound results in the formation of toluene. Different mechanisms are considered.

Inorganic Chemistry for Geochemistry and Environmental Sciences Fundamentals and Applications by George W. Luther III

Submitted by Rachel Narehood Austin / Barnard College, Columbia University on Wed, 01/04/2017 - 16:10
Description

This is a great new textbook by George Luther III from the University of Delaware.  The textbook represents the results of a course he has taught for graduate students in chemical oceanography, geochemistry and related disciplines.  It is clear that the point of the book is to provide students with the core material from inorganic chemistry that they will  need to explain inorganic processes in the environment.
