While the anodic trimerization of veratrole (leading to hexamethoxytriphenylene) is now a very well known reaction, developments concerning either mixed electrolysis (mixture of two orthodiethers) and/or oxidation of dissymmetrical substrates have not been conducted so far. The presented method, often specific, allows the synthesis of a new palette of liquid crystal precursors.
Construction of Unsymmetrical Triphenylenes from Electron-Rich Biphenyls and Diaryliodonium Salts via Copper-Catalyzed Multiple C–H Arylation
An efficient protocol to synthesize unsymmetrical triphenylenes from electron-rich biphenyls and diaryliodoniumsalts via Cu catalysis was developed. A variety of unsymmetrical triphenylenes with diversified functional groups were synthesized according to this method. This transformation went through multiple direct C–H arylations from easily produced starting materials with high step-economy. The
