The complex [(cymene)Ru(η 1 -indoline)(CH 3 CN) 2 ](OTf) 2, 1, has been synthesized by the reaction of [(cymene)Ru(OTf) 2 ] x with indoline in acid solution and characterized by an X-ray diffraction study. Bond distances for the indoline ligand are compared to those reported recently for other η 1 - and η 6 -indoline complexes. Complex 1 rearranged to [(cymene)Ru(η 6 -indoline)](OTf) 2 when heated in dichloromethane solution. The titration of an aqueous solution of 1 has been carried out, and the p K a of the coordinated ligand was determined to be 5.2. The value is similar to that reported for the indolinium ion. Ligand-exchange reactions of 1 have been studied. Deprotonation of the η 1 -indoline ligand in 1 results in dehydrogenation of the ligand to form free indole and ruthenium hydride products. The deprotonation of 1 in the presence of an alkene has been found to result in a hydrogen-transfer reaction to form alkane. Characteristics of the hydrogen-transfer reactions are discussed.
