This disclosure provides for processes to form a porous crosslinked polyphenoxide resin, using a templating process which can increase the porosity, pore size, active sites, and the like of the resin, as compared with a non-templated crosslinked polyphenoxide resin. The process includes contacting a phenol or polyphenol compound with formaldehyde and an aqueous base in the presence of a basic particulate template to form a templated crosslinked polyphenol resin. The templated crosslinked polyphenol resin can then be contacted with an aqueous acid to remove the basic particulate template and form a porous crosslinked polyphenol resin. This porous crosslinked polyphenol resin can subsequently be contacted with a metal-containing base to form a promoter for acrylate and acrylic acid formation from CO.sub.2 and ethylene coupling.

The present invention refers to a process for a transition metal, particularly nickel-catalyzed cyanation reaction of aryl/vinyl halide using organic nitrile compounds. This new reaction provides a strategically distinct approach to the safe preparation of aryl/vinyl cyanides, which are essential compounds in agrochemistry and medicinal chemistry.

A membrane includes a first layer, and a second layer coupled to the first layer. The second layer includes a network of catalytic sites, each catalytic site having a catalytic center characterized by promoting a chemical reaction of a target material. A method of forming a chemically reactive membrane includes applying a first solution to a structure, the first solution includes a macrocyclic ligand having electron-donating ligands and a side functional group for crosslinking, crosslinking a plurality of the macrocyclic ligand to form a first network of crosslinked macrocyclic ligands, and applying a second solution to the structure, the second solution comprising a catalytic center. Each catalytic center complexes with the electron-donating ligands of each macrocyclic ligand to form catalytic sites in the first network of crosslinked macrocyclic ligands.

Phosphine phosphonate and phenoxyphosphine ligands bearing polyethylene glycol (PEG) chains are used as described herein to produce heterobimetallic catalysts. The ligands can be metallated selectively with palladium or nickel and secondary metal ions to provide well-defined heterobimetallic compounds. These heterobimetallic complexes exhibit accelerated reaction rates and greater thermal stability in olefin polymerization compared to other catalysts.

The invention discloses a method for the preparation of fluoro alkylated compounds by homogeneous Ni catalyzed fluoro alkylation with fluoro alkyl halides in the presence of a base.

Provided are new nickel./zirconium-mediated coupling reactions useful in the synthesis of ketone-containing compounds, e.g., halichondrin natural products and related molecules. A feature of the present disclosure is the use of a nickel(I) catalyst in tandem with a nickel (II) catalyst in the Ni/Zr-mediated coupling reactions. Without wishing to be bound by any particular theory, the nickel (I) catalyst selectively activates the electrophilic coupling partner (i.e., the compound of Formula (A)), and the nickel(ll) catalyst selectively activates the nucleophilic coupling partner (i.e., a thioester of Formula (B)). This dual catalyst system leads to improved coupling efficiency and eliminates the need for a large excess of one of the coupling partners (i.e., a compound of Formula (A) or (B)).

A method for C—H bond activation and/or C—N coupling reaction comprises adding a hydrocarbon material to a container; adding a metal catalyst to the container; adding a primary or a secondary amine to the container. The metal catalyst is represented by the following formula:
