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.
Method for synthesizing 2,2'-dinaphthyl ether

Paragraph 0033-0038; 0040-0042, (2018/07/06)
The application relates to a method for synthesizing 2,2'-dinaphthyl ether. The method comprises the following specific steps: taking 2-naphthol and 2-bromonaphthalene as raw materials, adopting monovalent metal oxide and a diamine ligand as a catalyst system, and synthesizing to obtain the 2,2'-dinaphthyl ether by using an Ullmann diaryl ether synthesis method; then respectively adopting a separate purification scheme to avoid the use of chromatography. Products with the purity of 99 percent are obtained at the yield of nearly 70 percent, so the method has high industrial application value.
Bismuth(III)-catalyzed dehydrative etherification and thioetherification of phenolic hydroxy groups

supporting information, p. 3828 - 3831 (2014/08/05)
Use of a bismuth catalyst allowed efficient dehydrative substitution of phenolic hydroxy groups with alcohols and thiols to form C-O and C-S bonds. The reaction required equimolar amounts of two readily available substrates that generated H2O as the only byproduct. The relatively mild reaction conditions were compatible with the functional groups selected, and provided excellent chemoselectivity.
