Copper Nanoparticles from Copper Aluminum Hydrotalcite: An Efficient Catalyst for Acceptor- and Oxidant-Free Dehydrogenation of Amines and Alcohols
TL;DR: An efficient and simple process for the preparation of stable nanocopper(0) on alumina [Cu(0)/Al2O3] from the inorganic composite precursor copper aluminum hydrotalcite (Cu-Al HT) by a chemical reduction method is described in this paper.

Trifunctional N,N,O-terdentate amido/pyridyl carboxylate ligated Pd(II) complexes for Heck and Suzuki reactions.
TL;DR: Trifunctional N,N,O-terdentate amido/pyridyl carboxylate Pd(II) complexes were highly active and stable phosphine-free catalysts for Heck and room-temperature Suzuki reactions with high turnover numbers up to ca.

Silica immobilized copper complexes: Efficient and reusable catalysts for N-arylation of N(H)-heterocycles and benzyl amines with aryl halides and arylboronic acids
TL;DR: In this paper, the Cat2 was easily recovered by simple filtration and reused for several cycles with consistent activity, demonstrating the versatility of the protocol and demonstrating the usefulness of Cat2 for reusable catalysts.
