  名称：

  Syndiospezifische polymerisation von propylen: 3-, 4-, 3,4- und 4,5-substituierte zirkonocenkomplexe des typs (C13H8−nRnCR′2C5H4)ZrCl2 (n = 1,2; R  Alkyl, Aryl; R′  Me, Ph)

  摘要：

  Substituents in the positions 3, 4, 5 and 6 of the fluorenylidene fragment clearly influence the polymerization behaviour of the syndiospecific catalyst systems (C(13)H(8-n)R(n)CR(2)'C5H4)ZrCl2/MAO (n = 1, 2; R = alkyl, aryl; R' = Me, Ph). We report seven new catalyst precursors of this type, including first polymerization results. An X-ray study of the 4,5-dimethyl derivative 10b explains the reduced activity and stereospecifity of this catalyst.
