Theoretical study on hydrogenation catalysts containing a metal hydride as additional hydrogen supply [PDF]

open access: yes, 1992
A hypothetical hydrogenation catalyst consisting of porous, catalytically active particles embedded with metal hydride powder was evaluated. The metal hydride provides temporarily additional hydrogen if the mass transfer rate of the hydrogen to the ...

Accessing the main-group metal formyl scaffold through CO-activation in beryllium hydride complexes

open access: yesNature Communications, 2022
Stoichiometric carbon monoxide insertion processes leading to metal-formyl complexes are scarce, even for transition metals. Here, light is shed on the underexplored chemistry of beryllium hydrides leading to a stable example of a main group metal-formyl
