“…The hydrogen atoms linked to the boron were located directly, allowing the determination of a short ReÁ Á ÁH-B distance of 1.87(7) Å , which is comparable to the values reported for the bridging hydrides in [Re(CO)(PMe 3 ) 3 (j 2 -BH 4 )] (1.80(6) and 1.93(6) Å ) [16]. This short Re-H bond distance is consistent with the coordination of the agostic hydride, in agreement with the IR data obtained for 1.…”

The wavenumbers of 774 terminal hydride infrared active stretching modes of 478 distinct classes of structures of d6 octahedral complexes of Mn(I), Re(I), Fe(II), Ru(II), Os(II), Co(III), Rh(III), Ir(III), and Pt(IV) were collected from the literature. A fair correlation (R 2 0.95 with standard deviation 31 cm–1) is found for the data with the equation νMH calc = ν0 + Δν t + Δν n , where ν0 is the base wavenumber for the metal ion in question, Δν t is the parameter of influence of the ligand trans to the hydride, and Δν n is a correction for the charge of the complex [MHL5] n+. The introduction of a cis influence parameter has little effect on the correlation, showing that the trans influence dominates in this case. The equation is useful in identifying anomalous data reported in the literature, validating future assignments of νMH, understanding better metal-hydride bonding, and possibly assisting in identifying superior hydride-based catalysts.

“…A Lewis basicity trend for the hydride center of rhenium complexes was also tested by Berke and co-workers . Two isomers each of [Re(CO)(PMe 3 ) 4 H] ( 21 and 22 ) and [Re(CO) 2 (PMe 3 ) 3 H] ( 23 and 24 ), along with [Re(CO) 3 (PMe 3 ) 2 H] ( 25 ) (phosphines are trans oriented), were allowed to react with BH 3 and 9-BBN.…”

Main Group Lewis Acid-Mediated Transformations of Transition-Metal Hydride Complexes

This Review highlights stoichiometric reactions and elementary steps of catalytic reactions involving cooperative participation of transition-metal hydrides and main group Lewis acids. Included are reactions where the transition-metal hydride acts as a reactant as well as transformations that form the metal hydride as a product. This Review is divided by reaction type, illustrating the diverse roles that Lewis acids can play in mediating transformations involving transition-metal hydrides as either reactants or products. We begin with a discussion of reactions where metal hydrides form direct adducts with Lewis acids, elaborating the structure and dynamics of the products of these reactions. The bulk of this Review focuses on reactions where the transition metal and Lewis acid act in cooperation, and includes sections on carbonyl reduction, H2 activation, and hydride elimination reactions, all of which can be promoted by Lewis acids. Also included is a section on Lewis acid-base secondary coordination sphere interactions, which can influence the reactivity of hydrides. Work from the past 50 years is included, but the majority of this Review focuses on research from the past decade, with the intent of showcasing the rapid emergence of this field and the potential for further development into the future.
