摘要：

A family of ca. 50 imidotitanium precatalysts [Ti(NR)(Me-3[9]aneN(3))Cl-2] (R=alkyl or aryl; Me-3[9]aneN(3)=1,4,7-trimethyltriazacyclononane) were prepared in good yields using semiautomated procedures; high-throughput screening techniques identified seven highly active ethylene polymerisation precatalysts with activities in the range ca. 3 400 to 10 000 kg(PE) mol(-1) h(-1) bar(-1).
