Synthesis of metathesis catalysts with fluorinated unsymmetrical N,N’-diaryl imidazoline-based NHC ligands

Add time:08/04/2019    Source:sciencedirect.com

New olefin metathesis catalysts bearing unsymmetrical fluorinated NHC ligands with hexafluoroisopropylmethoxy group in ortho-positions of N-aryl-substituent have been synthesized. The effects of mono-ortho-arylsubstitution and the replacement of para-methyl N-aryl group with more electron-donating methoxy group in unsymmetrical fluorinated NHC ligand on the activity of complexes have been evaluated.
