This LO discuss various aspects of a reversible hydrogen activation by a metal-free phosphonium-borate compound. Attentions are paid to the specific and usual reaction between highly steric phosphine and borane reactants to form a zwitterionic phosphonium borate product. NMR spectroscopy, kinetics and thermodynamics of the hydrogen activation with the phosphonium borate product are also discussed. The original work was published in Science by Douglas W. Stephan and co-workers.
This collection accompanies the IONiC VIPEr nanoCHAt video series NeWBiEs, recorded in Spring 2022. This series is comprised of weekly conversations with two IONiC members, Wes Farrell and Shirley Lin from the US Naval Academy, as they taught a foundation-level inorganic chemistry course for the first time. The LOs discussed in the videos are included in this collection.
The course is currently designed for a student population impacted by COVID and College policies that the department offer this course every third semester. This semester I have a diverse student population in terms of developmental levels including cohort year (freshman, junior, senior), prior foundational course work (biochemistry, analytical, physical), and research experience. I have altered the assessment part of the course substantively from prior iterations and reduced topic coverage to provide flexibility.
In searching for a way to review topics before exams, I was informed about this powerpoint template which is macro'd to be operated as a realistic Jeopardy game. The site for the original author of the macro is:

A systematic study of both the fundamental principles and the descriptive chemistry needed to understand the properties of the main group elements and their compounds. (Three lecture, one recitation, and three laboratory hours per week) Prerequisites: CHEM 1200.
Inorganic chemistry is a branch of synthetic chemistry typified by its focus on compounds composed of elements other than carbon and hydrogen. But don’t let that fool you!
The O'Hare group has studied complexes of the permethylpentalene ligand, and recently reported the reaction of a zirconium complex of this ligand with CO2 to form the carbamate. A series of three different complexes were prepared, each with slightly different products upon reaction with CO2, illustrating subtle differences in reactivity based on either sterics or electronics. To further tangle the web, entropic and enthalpic considerations can also be considered.
This course will emphasize the fundamental concepts needed to understand the diverse chemistry of all the elements of the periodic table. The common theme for the entire course will be Structure and Bonding. The primary focus will be inorganic molecules, ions and solids, but the concepts we will discuss are applicable to all aspects of chemistry. The first two-thirds of the course will cover theories of bonding in molecules and solids along with some background in symmetry and structure.
A collection of all of the IONiC VIPEr NanoCHAts. These are short discussion on a teaching topic by 4-5 faculty members from different institutions. Each of these events is recorded and posted to the IONiC VIPEr YouTube Channel.
