A 2′-diarylphosphino-1,1′-biphenylen-2-yloxy(6,6′-divinyl-1,1′-binaphthalene-2,2′-diyloxy)phosphine derivative is disclosed, which is represented by general formula (I):
wherein Ar is an optionally substituted phenyl or naphthyl; R1 and R2 each independently is a hydrogen atom, a lower alkyl, a lower alkoxy, etc.; and R3 is a lower alkyl, a lower alkoxy, etc.; provided that R2 and R3 may be bonded to each other to form a hydrocarbon ring, which may have one or more substituents selected from lower alkyl groups, halogen atoms, vinyl, etc. Also disclosed are a polymer having structural units derived from the phosphine derivative and a transition metal complex obtained by causing a transition metal compound to act on the phosphine derivative.
一种2'-二芳基膦氧基-1,1'-联苯-2-亚氧基(6,6'-二乙烯基-1,1'-联萘-2,2'-二氧基)膦衍生物被公开,其由通用公式(I)表示:
其中Ar是可选地取代的苯基或萘基;R1和R2各自独立地是一个氢原子、低级烷基、低级烷氧基等;R3是低级烷基、低级烷氧基等;前提是R2和R3可以相互连接形成一个烃环,该环可以选择性地从一个或多个低级烷基组、卤素原子、乙烯基等中取代。还公开了一种由膦衍生物派生的结构单元的聚合物,以及通过使过渡金属化合物作用于膦衍生物而获得的过渡金属配合物。
