Properties of Metal Hydrides of the Iron Triad.

ABSTRACT: Metal hydride complexes are essential intermediates in hydrogenation reactions. The hydride-donor ability determines the scope of use of these complexes. We present a new, simple mass-spectrometry method to study the hydride-donor ability of metal hydrides using a series of 18 iron, cobalt, and nickel complexes with N- and P-based ligands (L). The mixing of [(L)M^II(OTf)₂] with NaBH₄ forms [(L)M^II(BH₄)]⁺ (M = Fe, Co, Ni) that can be detected by electrospray ionization mass spectrometry. Energy-resolved collision-induced dissociations of [(L)M^II(BH₄)]⁺ provide threshold energies (ΔE_CID) for the formations of [(L)M^II(H)]⁺ that correlate well
