The syntheses of trans-[Ru(C≡C-1-C6H4-4-N=N-1-C6H4-4-C≡C-1-C6H4-4-NO2)Cl(L2)2] (L2=dppm (Ru1), dppe) (Ru2)), trans-[Ru(C≡C-1-C6H4-4-N=N-1-C6H4-4-(E)-CH=CH-1-C6H4-4-NO2)Cl(dppe)2] (Ru3), and trans-[Ru(C≡C-1-C6H4-4-(E)-CH=CH-1-C6H2-2,6-Et2-4-N=N-1-C6H4-4-NO2)Cl(dppe)2] (Ru4) are reported, together with those of precursor alkynes. Their electrochemical properties were assessed by cyclic voltammetry (CV), linear optical and quadratic nonlinear optical (NLO) properties assayed by UV/Vis-NIR spectroscopy and hyper-Rayleigh scattering studies at 1064 nm, respectively, and their linear optical properties in the formally RuIII state examined by UV/Vis-NIR spectroelectrochemistry. These data were compared to those of analogues with E-ene and yne linkages in place of the azo groups. Computational studies using time-dependent density functional theory were undertaken on model compounds (Ru2′–Ru4′) to rationalize the optical behaviour of the experimental complexes.

Herein, we designed a simple nitrile synthesis from N-[(2-nitrophenyl)sulfonyl]benzamides via base-promoted intramolecular nucleophilic aromatic substitution. The process features redox-neutral conditions as well as no requirement of toxic cyanide species and transition metals. Our process shows broad scope and various functional group compatibility, affording a variety of (hetero)aromatic nitriles in good to excellent yields.
Zinc Oxide/Graphene Oxide as a Robust Active Catalyst for Direct Oxidative Synthesis of Nitriles from Alcohols in Water

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.]
