A straightforward two‐step synthesis of trans‐3,4‐disubstituted succinimides through a palladium‐catalyzed Sonogashira reaction and an iron‐catalyzed double carbonylation is described. In situ oxidative dehydrogenation gave the corresponding 3,4‐diarylmaleimides. By starting from readily available aryl and heteroaryl halides, a variety of new analogues and derivatives of bioactive 3,4‐bisindolylmaleimides
