[[alternative]]Reactions of crown ethers with five-membered heterocycles: 1H-imidazole-4,5-dicarbonitrile, 3-nitro-1,2,4-triazole and 1H-tetrazole

[[abstract]]By the reaction of 1H-imidazole-4,5-dicarbonitrile, 3-nitro-1,2,4-triazole, and 1H-tetrazole, containing one proton at each of the two proton-donating atoms separated by one covalent bond, it was shown that uncharged crystalline supramolecular compounds can be obtained on account of the proton-donating characteristics of the aromatic heterocycles.[[journaltype]]國外[[incitationindex]]EI[[booktype]]紙本[[countrycodes]]US
