Use of steric encumbrance to develop conjugated nanoporous polymers for metal-free catalytic hydrogenation.

Carboxylated polymers functionalized by cyclodextrins for the stabilization of highly efficient rhodium(0) nanoparticles in aqueous phase catalytic hydrogenation.

Rhodium(0) nanoparticles stabilized by a polymer containing carboxylate and β-cyclodextrin moieties have high stability and catalytic activity for aqueous hydrogenation reactions of olefins and aromatic substrates. This catalytic system can be recycled and reused without loss of activity. These high catalytic performances can be attributed to conjugated electrostatic interactions (carboxylate g...

Redox-Active Metal-Organic Nanostructure Polymers and Their Remarkable Electrochemical Behavior

A number of redox-active coordination polymers (CPs) or metal- organic frameworks (MOFs) have been successfully synthesized using transition metals and bridging ligands. This article aims to deal with gathering the aforementioned disperse issues regarding the electroactive CPs. It also goes towards illustrating the effects of various factors on the electrochemical behavior of CPs including...

Metal-free catalysts for hydrogenation of both small and large imines: a computational experiment.

This study extends our previous work of using π-FLP strategy to develop metal-free hydrogenation catalysts. Using small MeN=CMe(2) imine (im1) as a model, we previously designed cat1 and cat2 catalysts. But it is unclear whether they are capable of catalyzing the hydrogenations of bulky imines. Using tBuN=C(H)Ph (im2) as a representative of large imines, we assessed the energetics of the cat1- ...

Metal-free catalytic hydrogenation of enamines, imines, and conjugated phosphinoalkenylboranes.

Catalytic metal-free ketone hydrogenation: a computational experiment.

A computational study has been carried out to examine if the metal-free catalyst (1) designed for imine hydrogenation is able to hydrogenate ketones, using the cyclohexanone (3) and its derivatives (4-6) as ketone models. The catalytic cycle includes two major steps: hydrogen activation and hydrogen transfer. The concerted pathway in the hydrogen transfer step is preferred over the stepwise pat...
