Another element joins our expedition on main group Lewis acids! After Bi, Sb, Sn & Al, we now access a Ge(IV) centre using Tp! Ge shows superior activity than Sn(IV) in phosphine oxide deoxygenation, an intriguing reversal of expected down the group trend. doi.org/10.1039/D6DT...

Phosphanyl Radicals From Bismuth‐Mediated Reactions and Sterically Encumbered Diphosphanes
Reactions of LiPR2 with BiCl3 selectively give diphosphanes R2P–PR2 in high yields, presumably via Bi─P homolysis. This includes challenging cases with bulky substituents R. Sterically encumbered dip....

#Bismuth dications and CF3 groups: this combination yields Lewis superacids, record values in soft Lewis acidity (modified Gutmann-Beckett method) and pronounced catalytic activity in phosphane oxide reduction. Just out in @chemicalscience.rsc.org: pubs.rsc.org/sc/article/d.... Congrats to the team!

LOW-VALENT Si, Ge, Sn, Pb: HOW LOW CAN WE GO??? Hydrocarbon-soluble Mg(0) reduces Si all the way to Si(4-). Unfortunately not stable and decomposing to the HSi(3-) anion. However, Sn(4-) is stable and functions as 4-fold Nu or 8e reducing agent. Preprint: shorturl.at/4mH0O
