Synthesis and application of molybdenum (III) complexes bearing weakly coordinating anions as catalysts of isobutylene polymerization

Acetonitrile ligated molybdenum (III) complexes of the structure [MoCl(NCCH₃)₅]²⁺ bearing different weakly coordinating anions [B(C₆F₅)₄]⁻ (WCA a), [B{C₆H₃(m-CF₃)₂}₄]⁻ (WCA b) and [(C₆F₅)₃B-C₃H₃N₂-B(C₆F₅)₃]⁻ (WCA c) were applied as homogeneous catalysts of the polymerization of isobutylene. High mon...

Zusammenfassung:	Acetonitrile ligated molybdenum (III) complexes of the structure [MoCl(NCCH₃)₅]²⁺ bearing different weakly coordinating anions [B(C₆F₅)₄]⁻ (WCA a), [B{C₆H₃(m-CF₃)₂}₄]⁻ (WCA b) and [(C₆F₅)₃B-C₃H₃N₂-B(C₆F₅)₃]⁻ (WCA c) were applied as homogeneous catalysts of the polymerization of isobutylene. High monomer conversions were obtained in short reaction times (
