Abstract
A Pd-catalyzed method has been developed for the intramolecular oxidative coupling of 3- indolylarylketones under open air as terminal oxidant toward the synthesis of indeno [1, 2-b] indol-10 (5H)-ones. This reaction represents an intramolecular coupling with dual activation of C–H bonds for electron-deficient arenes, while such reactions are common for electron- rich arenes. Pd (II)-catalysis with pivalic acid as co-catalyst has been found to be crucial. ...
