The metal-hydride hydrogen atom transfer (MHAT) reaction plays an important role in the field of natural product synthesis. MHAT, as a powerful method, has been employed by chemists to construct C鈥揅, C鈥揌, and C鈥揾eteroatom bonds. In this review, we summarize the recent total ...
Many reactions of transition-metal hydrides involve H* transfer. With olefins such transfer gives a radical cage, from which escape and collapse lead to pr... DC Eisenberg,JR Norton - 《Israel Journal of Chemistry》 被引量: 105发表: 1991年 Hydrogen‐Atom Transfer Reactions of Transition‐Metal...
2. The ability to induce a concerted and efficient hydrogen atom transfer (HAT) process renders metal hydrides a hot spot in numerous catalytic reactions involving hydrogenation, hydrosilylation, and so on3,4,5. The advantage of being a hydride can be traced back to abundant enzyme activities ...
Metal surfaces catalyse polarization-dependent hydride transfer from H2 Article 17 April 2023 Introduction Metal hydrides play important roles in a wide range of energy and catalysis processes1,2. The ability to induce a concerted and efficient hydrogen atom transfer (HAT) process renders metal hydri...
Metal hydrides are key intermediates in catalytic proton reduction and dihydrogen oxidation. There is currently much interest in appending proton relays near the metal centre to accelerate catalysis by proton-coupled electron transfer (PCET). However, th
Although the organocatalyzed transfer hydrogenation using Hantzsch esters as hydrogen sources has made great progress in recent years, the use of stoichiometric amounts of hydrogen donors makes it less atom economical and thus likely restricts its application.7 In the past several years, a wide range...
and solvent-versatile reagent should allow an easier interface with existing radical reactions. Finally, isotope-labeling experiments rule out the alternative hypothesis of hydrogen atom transfer from a redox-active β-diketonate ligand in the HAT step. Instead, initial HAT from a metal hydride to ...
A critical evaluation of the location and refinement of a bridging hydrogen atom in a transition-metal hydride, .mu.-hydrido-.mu.-dimethylphosphido-bis(.eta.5-cyclopentadienyldicarbonylmolybdenum), by x-ray diffractionstructure (organic substances...
Such hydrogen-rich materials might be of interest for high-critical-temperature superconductivity if the gaps close under compression. Furthermore, the hydride complexes exhibit significant rotational motions associated with anharmonic librations at room temperature, which are often discussed in relation to...
To determine the hydrogen trapping energy (i.e., the energy difference between hydrogen at traps and in a ferrite lattice), we then placed a hydrogen atom in each of the carbon vacancies, with their varying numbers of neighboring Mo atoms, resulting in Fig.1g. We did not find that increas...
