Stereo-selectivity switchable ROP of: Rac -beta-butyrolactone initiated by salan-ligated rare-earth metal amide complexes: The key role of the substituents on ligand frameworks
A series of novel salan-ligated rare-earth metal amide complexes were prepared and employed as initiators for the ROP of rac-beta-butyrolactone (rac-BBL). Tuning the substituents on the N atoms of the ligand frameworks from aromatic groups to aliphatic groups results in switching tacticity from iso-tactic to syndio-tactic in rac-BBL polymerization.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, category: catalyst-ligand, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 150-61-8
