The discussion covers a 2021 publication by the Chirik group (Nature Chemistry, 2021, DOI: 10.1038/s41557-020-00614-w) which details the discovery of a new way to polymerize butadiene through iron-catalyzed [2+2] cycloadd

In this literature discussion, students are asked to explore the chemistry behind a eta-1 to eta-2 linkage photoisomer of sulfur dioxide bound to pentammine osmium. There are questions that tie to chemical structure and the nature of the two bonding modes of the ligand as well as an examination of the spectroscopic properties of the complex in the solid state. Two of the questions ask students to draw some conclusions based on their knowledge of periodic trends and the sigma donor ability of ligands.

This paper in Chemical Science written by Ellen Matson and co-workers describes a structure function approach to improving the properties of non-aqueous redox flow batteries based upon polyoxovanadate-alkoxides (POV-alkoxides). Given the importance of battery technology on society and sustainable chemistry, this article allows students to engage with a paper that could have broad implications in society.

This article provides an entry point for students to apply their knowledge of electron configurations and molecular orbital theory to the lanthanide and actinide elements. We have provided a large number of possible questions to use, grouped by theme.  Instructors can pick and choose questions that best fit their course.

This literature discussion explores the physical structure, electronic structure, and luminescent properties of a lanthanide coordination complex (dysprosium) through discussion of “Synthesis, Structure, Photoluminescence, and Electroluminescence Properties of a New Dysprosium Complex,” Li et al. J. Phys. Chem.
