New Sc(III) chloro-complexes [ScCl2(NNCp)(THF)] (1), [ScCl2(NNO)(THF)] (2) and [ScCl2(NNHO)(THF)] (3) {NNCp = 6-cyclopentadienylmethyl-pyridin-2-ylmethylene)-(2,6-diisopropyl-phenyl)-amine; NNO = 2-tert-butyl-6-((quinolin-8-ylimino)methyl)phenolate); NNHO = 2-tert-butyl-6-((quinolin-8-ylamino)methyl)phenolate} have been synthesized and characterized by NMR and mass spectrometry. The comparative results of the catalytic behavior of these scandium complexes towards ethylene and butadiene polymerization are reported and explained on the basis of the electronic and steric properties of the ancillary ligands.
New Sc(III) chloro-complexes with anionic polydentate [N,N,Cp] and [N,N,O] donor sets ligands [ScCl2(NNCp)(THF)], [ScCl2(NNO)(THF)] and [ScCl2(NNHO)(THF)] have been synthesized and characterized by NMR and mass spectrometry. The comparative results of their behavior as catalytic precursors in ethylene and butadiene polymerization are reported and explained on the basis of the electronic and steric properties of the ancillary ligands.Figure optionsDownload as PowerPoint slide
