The reaction of 2 equiv of lithium 1-phenylboratabenzene with ZrCl4 in ether affords bis(1-phenylboratabenzene)zirconium dichloride (2), while [4-tert-C4H9C5H4BPh]2ZrCl2 (3), obtained in a similar manner, was subjected to a single-crystal X-ray diffraction study. The reaction of a solution of 2 and methylaluminoxane (MAO) with C2H4 (1 atm, 25 °C) affords ethylene oligomers (dimers of 1-alkenes as the
2当量的1-苯基硼硼酸锂与ZrCl 4在乙醚中的反应生成双(1-苯基硼硼苯)二氯化锆(2),而[4-叔-C 4 H 9 C 5 H 4 BPh] 2 ZrCl 2(3)对以类似方式获得的α,进行单晶X射线衍射研究。2和甲基铝氧烷(MAO)的溶液与C 2 H 4(1 atm,25°C)的反应产生乙烯低聚物(以1-烯烃为主要产物的二聚物,以及少量的1-和2-烯烃) )。
