title: Asymmetric cleavage of 2,2'-pyridil to a picolinic acid anion radical coordinated to ruthenium(II): splitting of water to hydrogen.
abstract: The Ru(II)-H and water promoted asymmetric cleavage of 2,2'-pyridil to pyridine-2-carbaldehyde and unprecedented picolinic acid anion radical (PyCOOH(-)˙) complexes, which in solution produce H2 gas and diamagnetic picolinate complexes of ruthenium(II) in moderate yields, is reported.
