Triethylammonium‐1‐(2‐chlor‐1,3‐dioxo‐2‐indanyl)‐chlormethansulfonat (1b) und ‐dichlormethansulfonat (1a) wurden mit monofunktionellen, offenkettigen und cyclischen bifunktionellen Nucleophilen in einer neuartigen Reaktion zu den Bisacyl‐ketenacetal‐ bzw. Aminalstrukturen 2 und 5 bis 8 bzw. den Enaminoketon‐strukturen 4 umgesetzt.
A catalyst system useful for polymerizing olefins is disclosed. The catalyst system comprises an activator and a bimetallic complex that incorporates two Group 3 to 10 transition metal atoms, which may be the same or different, and a neutral or anionic indigoid ligand. By proper selection of the indigoid skeleton and by modifying its substituents and transition metal centers, polyolefin makers can fine-tune the bimetallic complexes to control activity, enhance comonomer incorporation, and optimize polymer properties.
