Article abstract of DOI:10.1002/ardp.19933260604

In the presence of 2,3-dichloro-5,6-dicyano-benzoquinone (DDQ) indazoles and benzotriazoles react with compounds forming stabilized carbenium ions like cycloheptatriene, di- and triphenylmethane, fluorene, xanthene and thioxanthene, yielding C-N-coupled products.
