Title:
N-HETEROCYCLIC BORYLOXY METAL COMPLEX AND PREPARATION METHOD THEREFOR AND USE THEREOF, AND COPOLYMERIZATION REACTION OF ETHYLENE AND NORBORNENE
Document Type and Number:
WIPO Patent Application WO/2024/061002
Kind Code:
A1
Abstract:
A N-heterocyclic boryloxy metal complex and a preparation method therefor and use thereof, and a copolymerization reaction of ethylene and norbornene. The N-heterocyclic boryloxy metal complex has a structure represented by formula (I), wherein R 1 is selected from hydrogen, substituted or unsubstituted C 1-C 10 alkyl, and substituted or unsubstituted C 6-C 12 aryl; Cp' is selected from substituted or unsubstituted cyclopentadienyl and derivatives thereof; M is selected from group IVB metal elements; R 2 and R 3 are each independently selected from halogen, substituted or unsubstituted C 1-C 10 alkyl, substituted or unsubstituted C 1-C 10 alkoxy, and substituted or unsubstituted benzyl. The N-heterocyclic boryloxy metal complex has relatively high structural stability and catalytic activity.
