    • The organo-Lewis acids are novel triarylboranes which are are highly fluorinated. Triarylboranes of one such type contain at least one ring substituent other than fluorine. These organoboranes have a Lewis acid strength essentially equal to or greater than that of the corresponding organoborane in which the substituent is replaced by fluorine, or have greater solubility in organic solvents. Another type of new organoboranes have 1-3 perfluorinated fused ring groups and 2-0 perfluorophenyl groups. When used as a cocatalyst in the formation of novel catalytic complexes with d- or f-block metal compounds having at least one leaving group such as a methyl group, these triorganoboranes, because of their ligand abstracting properties, produce corresponding anions which are capable of only weakly, if at all, coordinating to the metal center, and thus do not interfere in various polymerization processes such as are described.
    • 有机路易斯酸是高度氟化的新型三芳基硼烷。 一种这样的三芳基硼烷含有除氟以外的至少一个环取代基。 这些有机硼烷具有基本上等于或大于其中取代基被氟代替的有机硼烷的路易斯酸强度,或者在有机溶剂中具有更大的溶解度。 另一种新型有机硼烷具有1-3个全氟化稠环基团和2-0个全氟苯基。 当作为助催化剂用于与具有至少一个离去基团如甲基的d-或f-嵌段金属化合物形成新的催化络合物时,由于它们的配体抽出性质,这些三有机硼烷产生相应的阴离子,其能够 只有在与金属中心配位的情况下才是弱的,因此不会干扰如所述的各种聚合方法。
