摘要
Synthesis of 5,5 '-biindole was carried out by the Madelung indole reaction. Under strong basic conditions and high temperatures (350 degrees C), N,N '-bis-formyl-o-tolidine underwent cyclization to produce high amounts of the dimeric indole. Full and unambiguous assignments of all H-1- and C-13-NMR resonances of indole and 5,5 '-biindole in DMSO-d(6) are also reported.
