摘要：

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 CS2 with formation of complex [5]I featuring the CS2 molecule bound through the carbon atom to the MIC nitrogen atom and one sulfur atom coordinating to the platinum center.
