摘要:The present disclosure provides a preparation method of a doped ZnO catalyst. The preparation method includes the following steps: mixing a precipitant and a first solvent to form a first solution having 1 mol/L to 5 mol/L of the precipitant by concentration; mixing one of a Cu salt or a Ga salt, a Zn salt, and a second solvent to form a second solution having Cu and Zn at a molar ratio of less than 0.05:1 and Ga and Zn at a molar ratio of less than 0.1:1; subjecting the first solution and the second solution to precipitation or hydrolysis at 50° C. to 90° C. to obtain a precipitate, and washing and drying the precipitate to obtain a precursor sample; and conducting calcination on the precursor sample at 300° C. to 500° C. for 3 h to 5 h to obtain a Cu-doped ZnO catalyst or a Ga-doped ZnO catalyst.

摘要:One aspect of the present invention relates to novel reaction conditions that allow the efficient synthesis of diaryl ethers from arenes bearing a leaving group and arenols under relatively mild conditions. Another aspect of the present invention relates to the dramatic effects of acidic activators on Ullmann-type couplings involving electron-poor and/or relatively insoluble substrates.
