Syndiospezifische polymerisation von propylen; synthese CH2- und CHR-verbrückter fluorenylhaltiger Ligandvorstufen für metallocenkomplexe des Typs (C13H8−nR′nCHR-C5H4)ZrCl2 (n = 0, 2; R H, Alkyl; R′ H, Hal)

A convenient new one-pot synthesis makes accessible CH2- and CHR-bridged ligand precursors of the general formula C13H9−nR′nCHRC5H5 (n = 0, 2; R H, Alkyl; R′ H, Alkyl, Hal). From these the syndiospecific zirconocene catalysts (C13H8−nR′nCHRC5H4)ZrCl2 (n = 0, 2; R H, Me; R′ H, Br) for the polymerization of propylene can be prepared.
一个方便的新一锅合成使得可访问的CH 2 -和CHR-桥接通式C的配体前体13 ħ 9- Ñ R' Ñ CHRC 5 ħ 5(Ñ = 0,2; RH,烷基; R' H,烷基,Hal)。从这些间同立构二茂锆的催化剂(C 13 ħ 8- Ñ R' Ñ CHRC 5 ħ 4)的ZrCl 2(Ñ = 0,2; RH,甲基; R'为H,Br),用于丙烯的聚合可以准备。
