We report the C-H alkylation of biarylphosphines at the ortho' position(s) with alkenes by using rhodium(I) catalysis, which provides straightforward access to a large library of multifunctionalized phosphines. Some of these modified ligands outperformed commercially available phosphines in the Pd-catalyzed carboxylation of aryl bromides with carbon dioxide in the presence of a photoredox catalyst

Ambiphilic molecules, which contain a Lewis base and Lewisacid, are of great interest based on their unique ability to activate small molecules. Phosphine boronates are one class of these substrates that have interesting catalytic activity. Direct access to these phosphine boronates is described through the iridium‐catalyzed C−H borylation of phosphines. An unconventional cationic iridium catalyst

The present invention provides a process for effectively producing an N-(hetero)arylazole with high yield, which is useful as a medical or agrochemical product, an organic photoconductor material, an organic electroluminescent element material, or the like. The present invention relates to a process for producing an N-(hetero)arylazole, which includes reacting a (hetero)aryl (pseudo)halide with an NH-azole in the presence of: a catalyst including a palladium compound and a coordination compound; and a basic magnesium compound.
