Small Molecule Activation with N,NR‐MIC Platinum Complexes

Abstract

Abstract The reaction of platinum complex trans ‐[ 1 ] bearing an N,NEt‐imidazolide ligand with bis(diphenylphosphino)ethane (dppe) or bis(dicyclohexylphosphino)ethane (dchpe) yields the dinuclear MIC complexes [ 2 ]I 2 or the mononuclear MIC complex [ 3 ]I, respectively. Whereas dinuclear [ 2 ]I 2 does not react with elemental hydrogen, the mononuclear complex [ 3 ]I splits elemental hydrogen under mild reaction conditions with formation of hydride complex [ 4 ]I and N ‐ethylimidazole. Dinuclear complex [ 3 ]I activates CS 2 with formation of complex [ 5 ]I featuring the CS 2 molecule bound through the carbon atom to the MIC nitrogen atom and one sulfur atom coordinating to the platinum center.
