摘要

Potassium tert-butoxide mediated carbon–chalcogen C–E (E= O, S and Se) coupling reaction has been studied from aryl bromide and phenol/aryl disulfide/diselenide substrates. A series of unsymmetrical diaryl chalcogenides were accessed from aryl bromide and diaryl dichalcogenide precursors by using 2.5 equiv of potassium tert-butoxide in DMSO at 80° C. Unsymmetrical diaryl ethers were also obtained by using phenol precursors at 40–45° C. ...
