Synthesis of diaryl ethers, diaryl thioethers, and diarylamines mediated by potassium fluoride-alumina and 18-crown-6
摘要:
An efficient alternative to the copper-catalyzed synthesis (Ullmann ether synthesis) of diaryl ethers, diaryl thioethers, and diarylamines involving the potassium fluoride-alumina-mediated addition of a phenol, thiophenol, or an aniline to 2- or 4-fluorobenzonitriles catalyzed by 18-crown-6 is described.

nanoparticles in which both blue fluorescent cyanophenoxy and yellow/greenish-yellow fluorescent salicylidene group behave independently. 1 and 2 nanoparticles undergo morphological change from spherical to plates with increasing time. Thus, simple ESIPT molecules showed solid-state fluorescent and nanofabrication induced tunable fluorescence, particularly white fluorescent metastable nanoparticles.
