The Pd-catalyzed transformation of N-phthaloyl hydrazones into nitriles involving the cleavage of an N-N bond is reported. The use of N-heterocyclic carbene as a ligand is essential for the success of the reaction. N-Phthaloyl hydrazones prepared from aromatic aldehydes or cyclobutanones are applicable to this transformation, which gives aryl or alkenyl nitriles, respectively.

In this work, without using any linker or chemical modification of graphene oxide, a zinc oxide immobilized graphene oxide-based catalyst was used for the direct aerobic oxidative conversion of alcohols to the nitriles in water. In the first step, graphene oxide was prepared and then zinc ions were electrostatically adsorbed onto the surface of graphene oxide. In the following step, zinc oxide nanoparticles were generated via in-situ growth in presence of NaOH. It was illustrated that graphene oxide layers can control the size of in-situ generated zinc oxide nanoparticles. Various aromatic/aliphatic/heteroaromatic primary alcohols converted to the nitriles in high yields under O2 balloon with ZnO/GO catalyst. This catalyst can be used for 7 successful consecutive runs without significant loss of activity. Graphic Abstract: [Figure not available: see fulltext.]

An efficient method for catalyzing the ammoxidation of aromatic alcohols to aromatic nitriles was developed, in which a new heterogeneous catalyst based on transition metal elements was employed, the new catalyst was named Co-[Bmim]Br/C-700 and then characterized by X-ray photo-electronic spectroscopy, transmission electron microscope and X-ray diffraction. The reaction was carried out by two consecutive dehydrogenations under the catalysis of Co-[Bmim]Br/C-700, which catalytically oxidized the alcohol to the aldehyde, and then the aldehyde was subjected to ammoxidation to the nitrile. The catalyst system was suitable for a wide range of substrates and nitriles obtained in high yields, especially, the conversion rate of benzyl alcohol, 4-methoxybenzyl alcohol, 4-chlorobenzyl alcohol and 4-nitrobenzyl alcohol reached 100%. The substitution of ammonia and oxygen for toxic cyanide to participate in the reaction accords with the theory of green chemistry.
