Indoles are an important structural motif that is commonly found in biologically active molecules. In this work, conditions for divergentcouplings between imidamides and acceptor–acceptor diazo compounds were developed that afforded NH indoles and 3H‐indoles under ruthenium catalysis. The coupling of α‐diazoketoesters afforded NH indoles by cleavage of the C(N2)−C(acyl) bond whereas α‐diazomalonates
