In non-limiting examples, the method uses oxygen along with a catalytic system that includes palladium, an assistive ligand, and a non-palladium metal additive to catalyze one of the following reactions: ##STR00001## Associated catalytic systems and compositions are also disclosed.

Disclosed are methods of selective hydrodeoxygenation of aromatic compounds by using catalyst systems comprising N-heterocyclic carbene (NHC) and 4-pyridinol-derived pincer ligands and metal complexes containing these ligands.

Disclosed are novel analogs of cytisine, a process for their preparation, pharmaceutical compositions containing them, and their use in the prevention of or treatment of CNS disorders including addictive disorders.

Disclosed are methods of forming an epimer or a dehydrated isomer of a pyranose monosaccharide or a pyranose saccharide residue in an oligosaccharide or a glycoside.

The present disclosure is directed to method embodiments for making anhydrous lanthanide halide complexes. At least some embodiments comprise making a lanthanide halide complex by reacting a lanthanide metal oxide with an oxygen scavenger and catalyst in the presence of a donor solvent. The method is selective toward light lanthanide metal oxides and thus further provides a method for separating light lanthanide metal oxides from heavy lanthanide metal oxides, actinide oxides, and non-lanthanide rare earth element oxides.

A composition, method, and article of manufacture are disclosed. The composition includes a silica particle with light upconversion molecules bound to its surface. The method includes obtaining silica particles and light upconversion molecules having sidechains with reactive functional groups. The method further includes binding the light upconversion molecules to surfaces of the silica particles. The article of manufacture includes the composition.

Methods and catalysts for oxidizing ammonia to nitrogen are described. Specifically, diruthenium complexes that spontaneously catalyze this reaction are disclosed. Accordingly, the disclosed methods and catalysts can be used in various electrochemical cell-based energy storage and energy production applications that could form the basis for a potential nitrogen economy.

The subject invention provides synthetic compounds, and compound complexes having catalytic activities towards oxidation or oxygenation, and/or dehydrogenation of various substrates comprising C−H bonds. The catalysts of the subject invention comprise a dinuclear Cu(I)/Cu(II) center that can convert between a resting state and a reactive species. The subject invention also provides methods of using such catalysts for the oxidation of substrates comprising C−H bonds, e.g., hydrocarbons, to synthesize chemicals for use as pharmaceuticals and industrial feedstock.

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)).
