3′-bis-7-indolylmethane derivatives is important for their further development as pharmaceutical compounds and other synthetic purposes. Herein, we describe the zinc- or acid-mediated cross-coupling reaction of 7-azaindoles with aldehydes, such as paraformaldehyde, alkyl aldehydes, aryl aldehydes, enal, and α-ketoaldehyde, providing the corresponding C3-linked bis-7-azaindole derivatives, which are a crucial class

halogen bond-assisted electron-catalyzed iodination of heteroarenes has been developed for the first time under atom economic condition at room temperature. The iodination is successful with just 0.55 equiv of iodine and 0.50 equiv of peroxide. The kinetic study indicates that the reaction is elusive in the absence of a halogen bond between the substrate and iodine. The formation of a halogen bond, its
Diazo compounds play an important role as a coupling partner in the synthesis of unique π-conjugated 7-azaindole derivatives via rhodium(III)-catalyzed double C–H activation/cyclization.
