@sellathechemist@mastodon.social I suppose that's true enough! I was certainly surprised by the news (which I got from 200x chemical textbooks) that certain lanthanide salts were excellent Friedel-Crafts Lewis acid catalysts doing reactions conventionally done with vigorous AlCl3 treatment

@mxchara@seattle.pink There is a huge amount of activity in organic synthesis using different lanthanides salts - especially, but also complexes wrapped with chiral ligands - acting as Lewis acids to catalyze all manner of transformations. Sc(OTf)3 is particularly prized. Not cheap, mind. So it's got to be pretty good if people are going to use it. 😉 And then there's all the low-valent stuff with samarium to drive either radical reactions or Barbier-type processes with added reduction SmI2 is the bomb!
