Metal-Ligand Multiple Bonds: The Discovery of “Double Nickel” (Hillhouse)

Submitted by Anthony L. Fernandez / Merrimack College on Wed, 06/01/2022 - 00:52
Description

This LO focuses on creating complexes with multiple bonds between late transition metals and nitrogen. The questions will guide students through Mindiola and Hillhouse's communication that details the synthesis and investigation of three-coordinate terminal amido and imido complexes of nickel. This communication is significant because it describes the synthesis and structural characterization of what became known as his "double nickel" complex, which contains a Ni-N double bond.  

Substitution Chemistry in Odd-Electron Iron Group Carbonyl Complexes (D'Acchioli)

Submitted by Nancy Williams / Scripps College, Pitzer College, Claremont McKenna College on Sun, 05/29/2022 - 05:54
Description

This LO brings together organometallic chemistry, electrochemistry, and computational chemistry in a complete whole, and shows how these different expertises and techniques all can add to our understanding of a rich chemical system. It might be of particular interest in a class dominated by even-electron and diamagnetic chemistry to give students an understanding of how practitioners approach odd-electron, paramagnetic systems. 

Discussion of "Dirhodium(II/II)/NiO Photocathode for Photoelectrocatalytic Hydrogen Evolution with Red Light" (Turro)

Submitted by Jason D'Acchioli / University of Wisconsin-Stevens Point on Sat, 05/21/2022 - 12:13
Description

This Learning Object is dedicated to Prof. Claudia Turro as part of the VIPEr LGBTQIAN+ LO collection created in celebration of Pride Month (Jun) 2022. Prof. Turro was featured in the April 2022 special virtual issue Out in Inorganic Chemistry: A Celebration of LGBTQIAPN+ Inorganic Chemists (https://pubs.acs.org/doi/10.1021/acs.inorgchem.2c00729). Claudia holds a special place in my heart. I came out later in life, and she was incredibly supportive as I wrestled with my identity as a gay man.

Mechanistic Study of Competitive sp3-sp3 and sp2-sp3 Carbon-Carbon Reductive Elimination from a Platinum(IV) Center and the Isolation of a C-C Agostic Complex (Williams)

Submitted by Shirley Lin / United States Naval Academy on Fri, 05/20/2022 - 08:09
Description

This literature discussion focuses on a J. Am. Chem. Soc. communication that describes a series of Pt complexes that exhibit competitive reductive elimination reactions to form either an sp2-sp3 bond or an sp3-sp3 bond. One of the complexes also contains a C-C agostic interaction with the metal. The questions are written to be addressed by students in a foundation-level inorganic course.

SLiThEr #20: African American Chemists: Academia, Industry, and Social Entrepreneurship

Submitted by Chip Nataro / Lafayette College on Tue, 06/15/2021 - 07:33
Description

Sibrina Collins (Lawrence Tech) presented a SLiThEr on April 10, 2021. The topic was her recently releases ACS Symposium Series book entitled "African American Chemists: Academia, Industry, and Social Entrepreneurship". Sibrina presented on stories, both hearing them and telling them. She recounted how she used the VIPEr model of learning objects to make the stories in the book accessible for use in the classroom. 

SLiThEr #16: Scaffolding oral exams in general chemistry
