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.

Upcoming SLiThErs

Submitted by Chip Nataro / Lafayette College on Thu, 04/07/2022 - 13:53

After a brief break due to a live ACS meeting and the struggle to try to catch up after that meeting, it is time to have our next SLiThEr. For those of you who might be unfamiliar with what a SLiThEr is, it is a Zoom presentation/discussion of a topic of interest to the community. These events are recorded and posted to our YouTube channel. You can get a list of past SLiThErs and links to the videos here. For April, our SLiThErs have a theme of inclusivity.

Catalytic Transformation of Lignin (Abu Omar)

Submitted by Hilary Eppley / DePauw University on Tue, 03/15/2022 - 10:20
Description

Lignin material from plants may be transformed into useful organic materials.  This LO is part of a special VIPEr collection honoring the 2022 ACS National Award recipients in the field of inorganic chemistry. Mahdi Abu Omar was the recipient of the ACS Award in Green Chemistry for his contributions to fundamental science and technology development for catalytic lignin conversion to renewable chemicals, fuels, and materials following green chemistry and engineering principles. 

The ditungsten tetracarboxylate story (Sattelberger)

Submitted by Joanne Stewart / Hope College on Tue, 03/15/2022 - 09:37
Description

This literature discussion learning object examines the first reported synthesis in 1983 of the long anticipated quadruply bonded ditungsten tetracarboxylate dimers by Dr. Al Sattelberger and co-workers. This LO is part of a special VIPEr collection honoring the 2022 ACS National Award recipients in the field of inorganic chemistry. Alfred P. Sattelberger was the recipient of the 2022 ACS Award for Distinguished Service in the Advancement of Inorganic Chemistry.

Enhancement of the Thermal Stability and Thermoelectric Properties of Yb14MnSb11 by Ce Substitution (Kauzlarich)

Submitted by Susan Kauzlarich / University of California, Davis on Mon, 03/14/2022 - 20:57
Description

This article provides an introduction to thermoelectric materials and applications for space, highlighting a complex Zintl phase, Yb14-xCexMnySb11. Yb14MnSb11 is a semiconductor that can be substituted with Ce to change the number of carriers in the material and thereby enhance the transport properties.

Spectroscopic, Structural, and Computational Analysis of [Re(CO)3(dippM)Br]n+ (Nataro)

Submitted by Shirley Lin / United States Naval Academy on Sat, 03/12/2022 - 06:17
Description

This literature discussion will guide students through an article that applies spectroscopic, structural, and computational analyses to a family of compounds of the type [Re(CO)3(dippM)Br]n+  (dippM = 1,1’-bis(diisopropyl)phosphino metallocene, M = Fe, n= 0 or 1; M = Co, n = 1).

Toward the Design of Phosphorescent Emitters of Cyclometalated Earth-Abundant Nickel(II) and Their Supramolecular Study (Yam)

Submitted by Kyle Grice / DePaul University on Tue, 03/08/2022 - 15:15
Description

This LO was created to celebrate Dr. Vivian W.-W. Yam's 2022 ACS Award, the Josef Michl Award in Photochemistry. These questions are written to help guide class discussion about this paper and the complexes in it. This LO would be good for an organometallics class or similar upper-division inorganic chemistry class.
