Twelve diaza‐15‐crown‐5 and 18‐crown‐6 macrocycles containing different side arms on the nitrogen atoms have been prepared. These diaza‐ N,N' ‐di pivot lariat crown ethers were prepared either from N,N' ‐bishydroxyethyl‐1,4‐diaza‐15‐crown‐5 or 18‐crown‐6 ligands or from the corresponding unsubstituted diaza‐crowns.
