The C(sp3)‐H bond decyanative arylations of diverse symmetrical and unsymmetrical BIMs have been successfully accomplished. Aromatic nitriles were utilized as components in the presence of thiobenzoic acid (TBA) under visible‐light irradiation. These redox‐neutral protocols provide a highly efficient and practical strategy for the synthesis of a broad range of bis(indolyl)‐substituted and mono(indolyl)‐substituted hetero‐triarylmethanes. Moreover, this synthetic approach has been expanded to the construction of indole‐substituted triarylmethanes bearing all‐carbon quaternary stereocenters. It is noteworthy that the preparation of the natural product Arsindolin A was effectively achieved using this methodology.
