New methodologies and approaches to reaction discovery in transition metal catalysis
… palladium catalysts enable the coupling of aryl boronate esters formed from iridium-catalyzed C-H borylation to be coupled with various allylic halides, allylic carboxylates and benzylic halides. Nickel catalysts bearing diamine or phenanthroline- based ligands have been used to couple these aryl …
