A Highly Lewis Acidic Strontium ansa‐Arene Complex for Lewis Acid Catalysis and Isobutylene Polymerization

The potential of a dicationic strontium ansa‐arene complex for Lewis acid catalysis has been explored. The key to its synthesis was a simple salt metathesis from SrI(2) and 2 Ag[Al(OR(F))(4)], giving the base‐free strontium‐perfluoroalkoxyaluminate Sr[Al(OR(F))(4)](2) (OR(F)=OC(CF(3))(3)). Addition...

description The potential of a dicationic strontium ansa‐arene complex for Lewis acid catalysis has been explored. The key to its synthesis was a simple salt metathesis from SrI(2) and 2 Ag[Al(OR(F))(4)], giving the base‐free strontium‐perfluoroalkoxyaluminate Sr[Al(OR(F))(4)](2) (OR(F)=OC(CF(3))(3)). Addition of an ansa‐arene yielded the highly Lewis acidic, dicationic strontium ansa‐arene complex. In preliminary experiments, the complex was successfully applied as a catalyst in CO(2)‐reduction to CH(4) and a surprisingly controlled isobutylene polymerization reaction.
