On the Nature of the Formation of [(η5-Ind)Ru(CO)2H]: Evidence of a Water-Gas Shift Reaction Mechanism via Triethylamine Reduction

The formation of [(η5-Ind)Ru(CO)2H] from [(η5-Ind)Ru(CO)3]+ was investigated using both 1H and 2H NMR spectroscopy and GC−mass spectrometry. Both NMR and GC-MS data support a water-gas shift reaction mechanism as the cause for formation of [(η5-Ind)Ru(CO)2H].
