An Acid-stable Organoruthenium Complex Suitable as a Bidentate Building Block
A new, water-soluble organoruthenium(II) sulfato complex [Ru II (SO 4 )(Bz^py)] {1, Bz^py = 2-(pentamethylbenzyl)pyridine has been synthesized and is stable at pH from 2.0 to 8.0. This complex has a bidentate sulfato ligand as a leaving group and is a good building block for "concerto catalysis": a new way of thinking in catalysis that bridges hetero- and homogeneous catalysis.
