Self-encapsulation of homogeneous catalyst species into polymer gel leading to a facile and efficient separation system of amine products in the Ru-catalyzed reduction of carboxamides with polymethylhydrosiloxane (PMHS)

A practical procedure for production of amines is offered by the ruthenium-catalyzed reduction of carboxamides with polymethylhydrosiloxane, in which encapsulation of the catalyst species into the formed insoluble siloxane resins contributes to the separation of both metallic and siloxane residues from the product.     

Selective reduction of aqueous protons to hydrogen with a synthetic cobaloxime catalyst in the presence of atmospheric oxygen

Protons preferred: A cobalt catalyst is reported that evolves H(2) electro- and photocatalytically at room temperature, in pH-neutral water, and in the presence of atmospheric O(2) . The catalyst shows respectable Faradaic efficiencies under N(2) and 21?% O(2) in N(2) , and can be used under both homogeneous and heterogeneous conditions.
