The Question of the Cr Oxidation State in the {Cr(SNS)} Catalyst for Selective Ethylene Trimerization: An Unanticipated Re‐Oxidation Pathway

Abstract

Wieder aktiv werden! Die erstmals beobachtete Oxidation von Chrom(II) durch Trimethylaluminium führt ungeachtet der reduzierenden Umgebung zu einem kationischen Organochrom(III)-Komplex (siehe Bild; SNS=CySCH2CH2N(H)CH2CH2SCy, Cy=Cyclohexyl, X=[Me6Al2Cl]). Diese Reaktion bietet einen möglichen Weg zur Reaktivierung des Katalysators.
