Cation-switchable transposition and hydrogenation of alkenes <i>via</i> interconnected reaction mechanisms.

ABSTRACT: Cation-switchable catalysis is a promising strategy for modulating reaction rates or selectivity using external stimuli, with potential applications including polymer synthesis and tandem catalysis. This study establishes a deeper understanding of the mechanistic origins of cation rate promotion in systems where a hemilabile crown ether affixed to the catalyst serves as a cation receptor site, which in turn enables reactivity extensions of this platform to introduce cation-switchable alkene hydrogenation. The mechanistic study hinges on the synthesis of two previously unreported iridium(iii) complexes, bearing either bis(2-methoxyethyl)amine or diethylamine groups, which could be compared in catalysis with and without cation promoters. Only the catalyst containing a crown ether exhibits sw
