Chromium complexes supported by phenanthrene-imine derivative ligands: Synthesis, characterization and catalysis on isoprene cis-1,4 polymerization

Article abstract of DOI:10.1039/c2dt11365a

Reactions of CrCl₂(THF)₂ with N-aryl-9,10- iminophenanthraquinone in CH₂Cl₂ give the monoimine chromium complexes ^ArIPQCrCl₂(THF)₂ (1, Ar = 2,6-Me₂C₆H₃
