There is a strong incentive for environmentally benign and sustainable production of organic nitriles to avoid the use of toxic cyanides. Here we report that manganese oxide nanorod-supported single-site Ru catalysts are active, selective, and stable for oxidative cyanation of various alcohols to give the corresponding nitriles with molecular oxygen and ammonia as the reactants. The very low amount of Ru (0.1 wt %) with atomic dispersion boosts the catalytic performance of manganese oxides. Experimental and theoretical results show how the Ru sites enhance the ammonia resistance of the catalyst, bolstering its performance in alcohol dehydrogenation and oxygen activation, the key steps in the oxidative cyanation. This investigation demonstrates the high efficiency of a single-site Ru catalyst for nitrile production.

Ullmann-type diaryl ether synthesis was performed under mild conditions in DMF/K2CO3using a pyridinefunctionalized silane as a ligand. The productswere obtained in good yields. This method tolerates a variety of functional groups and is effective in the synthesis of hindered diaryl ethers and heteroaryl ethers.

An efficient methodology has been developed for the synthesis of nitriles through an aerobic oxidative reaction of alcohols and ammonium formate with copper as a homogeneous catalyst under a normal air atmosphere and solvent-free conditions. This protocol uses the air as a green oxidant and ammonium formate as the nitrogen source. A wide range of substrates were well tolerated in the reaction that gave water as a byproduct. A facile protocol, which uses copper as an effective homogeneous catalyst, has been developed for the oxidative synthesis of nitriles from alcohols and ammonium formate. This system uses air as a green oxidant and produces water as an environmentally benign side product. Copyright
