Diaryl Ether Formation Merging Photoredox and Nickel Catalysis

Photoredox and Ni catalysis are combined to produce diaryl ethers under mild conditions. A broad range of aryl halides and phenol derivatives are cross-coupled in the presence of a readily available organic photocatalyst and NiBr2(dtbpy). Symmetrical diaryl ethers have also been directly obtained from aryl bromides in the presence of water. Mechanistic investigations support the involvement of Ni(0) species at the outset of the reaction and a Ni(II)/Ni(III)-photocatalyzed single electron transfer process preceding the productive C(sp2)-OAr reductive elimination.

A soluble copper(I) source and stable salts of volatile ligands for copper-catalyzed C-X couplings

A stable adduct of CuI with Bu4NI, soluble in organic solvents, has been identified as an effective catalyst for copper-catalyzed C-N and C-O couplings. In addition, stable nonhygroscopic salts of some high performance ligands (diamine MsOH salts/CuX and copper(II) diketonates) were shown to be of similar and sometimes greater reactivity compared to the literature reagents for these couplings. Furthermore, these more robust conditions result in more reproducible results.
