Treatment of the dibenzyl compounds [(ArO)2M(CH2Ph)2] (ArO = 2,6-diphenyl-3,5-dimethylphenoxide, M = Ti, Zr; ArO = 2,6-diphenylphenoxide, M = Ti) with [B(C6F5)3] gave the corresponding zwitterionic species [(ArO)2M+(CH2Ph)(η6-C6H5CH2B-(C6F5)3)]. Addition of [B(C6F5)3] to the titanium dimethyl compounds [(ArO)2TiMe2] gave unstable species which polymerize ethene and propene.
二苄基化合物[(ArO)2 M(CH 2 Ph)2 ]的处理(ArO = 2,6-二苯基-3,5-二甲基苯氧化物,M = Ti,Zr; ArO = 2,6-二苯基苯氧化物,M = Ti )与[B(C 6 ˚F 5)3 ],得到相应的两性离子物种[(ARO)2中号+(CH 2 PH)(η 6 -C 6 H ^ 5 CH 2乙-(C 6 ˚F 5)3)] 。在钛二甲基化合物[(ArO)2中添加[B(C 6 F 5)3 ]TiMe 2 ]得到不稳定的物质,其使乙烯和丙烯聚合。
