A convenient Ni(II)‐catalyzed C−C and C−N cascade couplingreaction was developed to directly access various 2,4‐disubstituted imidazoles. The reaction scope covers a variety of aryl and aliphatic substitutions, which demonstrate moderate‐to‐excellent yields. The tolerance of halogen and N‐containing heterocyclic groups demonstrates the versatility of this method for further synthetic explorations
