An efficient protocol to synthesize unsymmetrical triphenylenes from electron-rich biphenyls and diaryliodonium salts 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 gram-scale synthesis of triphenylenes and their facile transformation into diverse functional organic molecules were illustrated.
发展了一种通过 Cu 催化从富电子联苯和二芳基碘鎓盐合成不对称三联苯的有效方法。根据该方法合成了多种具有不同官能团的不对称三联苯。这种转化从易于制备的起始原料中经过多次直接 C-H 芳基化反应,具有很高的步骤经济性。还展示了三联苯的克级合成及其易于转化为多种功能有机分子。
