摘要：

In the oligomerization of propylene by (C5Me5)2MCl2 (M = Zr, Hf) /methylalumoxane, formation of abnormal oligomers such as 1-pentene(C5), 2,4-dimethyl-1-pentene(C7), 4-methyl-1-heptene(C8), and 2,4,6-trimethyl-1-heptene(C10) besides normal oligomers such as 4-methyl-1-pentene(C6) and 4,6-dimethyl-1-heptene(C9) is indicative of the mixing of unusual beta-CH3 and usual beta-H transfer terminations from each growing carbon chain which was initiated by insertion of propylene into either M-H or M-Me bond.
