Although reversible covalent activation of molecular hydrogen (H2) is a common reaction at transition metal centers, it has proven elusive in compounds of the lighter elements. We report that the compound (C6H2Me3)2PH(C6F4)BH(C6F5)2 (Me, methyl), which we derived through an unusual reaction involving dimesitylphosphine substitution at a para carbon of tris(pentafluorophenyl) borane, cleanly loses H2 at temperatures above 100°C. Preliminary kinetic studies reveal this process to be first order… Expand
On the origin of reversible hydrogen activation by phosphine-boranes.
TLDR
Mechanistic insights into the factors responsible for the reversible hydrogen-activation ability exhibited by an aryl phosphine-borane system are presented and computed thermodynamic parameters are found to be in accordance with the experimental observations. Expand
Facile Splitting of Hydrogen and Ammonia by Nucleophilic Activation at a Single Carbon Center
TLDR
It is shown that more nucleophilic and electrophilic (alkyl)(amino)carbenes can activate H2 under mild conditions, a reaction that has long been known for transition metals. Expand
H2 Activation by Non-Transition-Metal Systems: Hydrogenation of Aldimines and Ketimines with LiN(SiMe3 )2.
TLDR
Mechanical investigations indicated that the reaction proceeds via a lithium hydride intermediate as the actual reductant, and tolerates the presence of acidic protons in the α-position. Expand
Homolytic cleavage of peroxide bonds via a single electron transfer of a frustrated Lewis pair.
Single electron transfer (SET) reactions are effected by the combination of a Mes3P/B(C6F5)3 frustrated Lewis pair with benzoyl peroxide derivatives. The resulting homolytic cleavage of the peroxideExpand
Hydrogenation of CO2 to Formate with H2 : Transition Metal Free Catalyst Based on a Lewis Pair.
TLDR
The first catalytic hydrogenation process of CO2 to formate using transition metal free catalyst (BCF/M2 CO3, M=Na, K, and Cs) is reported and the highest TON value of this catalytic process is up to 3941. Expand
Hydrogen activation by an aromatic triphosphabenzene.
TLDR
Density functional theory (DFT) calculations show that facile distortion of the planar triphosphabenzene toward a boat-conformation provides a suprafacial combination of vacant acceptor and donor orbitals that permits this direct and uncatalyzed reduction of the aromatic molecule. Expand
Splitting of multiple hydrogen molecules by bioinspired diniobium metal complexes: a DFT study.
TLDR
Using quantum chemical modeling, it is shown that low-valent, early transition metal diniobium(ii) complexes with diphosphine ligands featuring pendant amines can favorably uptake up to 8 hydrogen atoms, and that the energetics are favored by the formation of intramolecular dihydrogen bonds. Expand
On the mechanism of B(C6F5)3-catalyzed direct hydrogenation of imines: inherent and thermally induced frustration.
TLDR
The reaction mechanism for the transition metal free direct hydrogenation of bulky imines catalyzed by the Lewis acid B(C6F5)3 is investigated in detail by quantum chemical calculations, and the results provide solid support for the imine reduction pathway proposed from experimental observations. Expand
Reversible Hydrogen Activation by a Pyridonate Borane Complex: Combining Frustrated Lewis Pair Reactivity with Boron-Ligand Cooperation.
TLDR
DFT and DLPNO-CCSD(T) computations reveal that the active form of the pyridonate borane complex is a boroxypyridine that can be described as a single component frustrated Lewis pair (FLP), and this unprecedented mode of action may be regarded as an example of boron-ligand cooperation. Expand
Alkali Metal Species in the Reversible Activation of H2.
TLDR
DFT calculations reveal that these systems effect H2 activation via cooperative interactions with the Lewis acidic alkali metal and the basic phosphorus, carbanion, or hydride centres, mimicking frustrated Lewis pair (FLP) behaviour. Expand

Mössbauer studies of the iron-sulfur cluster-free hydrogenase: the electronic state of the mononuclear Fe active site.
TLDR
The iron-sulfur cluster-free hydrogenase (Hmd) from methanogenic archaea harbors an iron-containing, light-sensitive cofactor of still unknown structure as prosthetic group, which excludes that the iron in the active site of Hmd is Fe(I), high-spin Fe(0), or high- spin Fe(II). Expand
