nBu4NI-catalyzed intramolecular cross-dehydrogenativecoupling (CDC) reaction has been applied to the synthesis of 1H-indole derivatives. Intramolecular oxidative coupling of N-arylenamines proceeded in the presence of a catalytic amount of nBu4NI and tert-butyl hydroperoxide (TBHP) to afford the corresponding 1H-indole derivatives in good-to-excellent yields. A preliminary study of the synthesis of 3H-indole is also
