Novel zirconium complexes derivedfrom C2-symmetric diamide ligands; the X-ray crystal structure of [Zr(η1-CH2Ph)(η2-CH2Ph){(C6H3)2-2,2′-(NCH2C6H4Ph-4)2-6, 6′-Me2}]
摘要:
The novel alkene polymerisation cocatalysts [Zr(CH(2)Ph)(2)(ArDABP)] containing the biphenyl-bridged ligands 2,2'-di-(N-benzyl)amino-6,6'-dimethylbiphenyl (ArDABP, Ar = CH(2)C(6)H(4)(t)Bu-4 or CH2C6H4-Ph) display averaged C-2-symmetry in solution and an eta(2)-benzyl coordination mode in the solid state.
