Abstract
Indigo in which O is replaced by C(CN)2 (1) or NCN was prepared for the first time. Both compounds and their derivatives absorb in the near‐IR at considerably longer wavelengths than indigo. Attempts to synthesize the analogous thioindigo derivatives led to compounds 2‐4 (X = S, SO2) by reaction sequences that were sometimes unexpected.
