A couple of things I don't get about that molecule (HOCPrCA):
- is it a double radical, cause if those are two free adjacent electrons, isn't that just a bond? Is there like a chaperone molecule to stablize it normally, otherwise it all seems ridiculously reactive.
- its R,R-isomer is stereochemically made .. selectively, but how is it even a chiral molecule cause it looks planar trigonal?
A radical is denoted with a dot. The star means it's chiral. And yes two electrons would pair up.
It's chiral. With two enantiomers and a meso.
