An
efficient synthesis of a variety of dibenzofuran derivatives
via Cu-catalyzed cyclization diaryliodonium salts in water is achieved.
Various dibenzofuran derivatives could be obtained in good to excellent
yields via this oxygen–iodine exchange approach. A concise
synthesis of organic semiconducting material molecule has been achieved
using this method.
The effi cient reuse of homogeneous catalyst is important. P-NMR), element analysis (EA), and high resolution mass spectrometry (HR-MS). The complex was used as a catalyst for the hydrogen transfer reduction of carbonyl for the fi rst time, presenting an excellent catalytic performance of 89%-98% conversion of acetophenone and its derivatives. The catalyst may be effi ciently reused by the electro-adsorption of 10 times to one catalyst recovery. The cation [Ru] complex presented advantages of both homogeneous and heterogeneous catalysts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
