Aluminum: lightest p-block metal with very low electronegativity. Converting Al(III) to Al(I) in stoichiometric reactions is rare. But now, we've made Al redox catalysis a reality! Check it out @nature nature.com/articles/s41586-0…

Since my days as a graduate student, I have been interested in using carboranes as substituents on heteroatoms to tune electronics, similar to classical alkyl and aryl groups. Over the years, our group and others have demonstrated that C-bound carboranes are actually strongly electron withdrawing, comparable to classical perfluoroarenes. In our latest preprint (tinyurl.com/2mndp5j2), Vicki Rubio shows that this concept extends to the heavy pnictogens, revealing that carborane substitution allows for the construction of highly Lewis acidic Sb(V) centers. A special shout out goes to all coauthors and especially Osvaldo Gutierrez and his team for their contributions to the theoretical and computational aspects of this work.

Congrats to Lan, Matt, Grace, Ashley, and Lamia! Want to highlight here that Grace, an undergrad @UCRiverside, did the heavy lifting on revisions while Lan was on internship. Grace is applying for grad school this year and any program would be lucky to have her!

Can redox active, Lewis acidic magnesium Pac-man complexes form stable "adducts" with alkanes? Jeremy, Matt, Joe and co’s latest pre-print @ChemRxiv says ”Hell Yeah”! Alkane C-H activation by a main group metal incoming? tinyurl.com/3f4c22sz #ozchem @ChemistryMonash @AFOSR

In our latest preprint, we introduce rhodamines as new scaffolds for molecular electronics. We harness rhodamine's lactone-zwitterion bistability to access on/off conductance ratios that are among the highest reported for chemically-induced switches. tinyurl.com/7r4wbpeb
