Eco-friendly synthesis of hierarchical CuO nanoparticles using the peel of Musa balbisiana and its application as a nanocatalyst in oxidation of aldehyde to the corresponding carboxylic acid is reported here. CuO nanoparticles were characterized by using XRD, XPS, SEM, TEM and PL techniques. In XRD analysis, significant peaks appeared at 18.2, 24.6, 33.3, 34.9, 35.5, 38.6 and 42.3. The SEM images indicate the formation of a micro flower hierarchical CuO architecture. The hierarchical CuO architecture is found to be made up of 2D nanosheets as building blocks, which were self assembled to form micro flower like assemblies. The synthesized CuO nanoparticles are efficiently utilised in the oxidation of aldehyde to the corresponding carboxylic acid in the presence of 30% H2O2 with high yields. The utilization of the CuO nanocatalyst in the oxidation reaction in environmental friendly conditions is the novelty in this study. This journal is the Partner Organisations 2014.

Two nitrogen-rich energetic compounds with π-stacking, 1,1′-dichloro-2,2′,3,3′,6,6′-hexanitro-5,5′-dihydroxyazobenzene (1) and 8-(2,4,6-triazido-3,5-dinitrophenyl)-8H-[1,2,3]triazolo[4′,5′:5,6]benzo[1,2-c:3,4-c′]bis([1,2,5]oxadiazole) 1,4-dioxide (2), were prepared by a novel synthesis method, and their structures were determined by single-crystal X-ray diffraction analysis. The decomposition temperature of 1 is 336 °C and 2 exhibits excellent heat of formation of 1160.5 kJ mol?1 (2.21 kJ g?1). The condensation reaction of the coupling of a N═N bond and an azido from 1 to 2 was proved to be an efficient method to synthesize benzotriazole. This synthetic strategy for benzotriazole may arouse considerable interest in the area of organic synthesis.

Aryl-triazole oligomers based on isobutyl 4-fluorobenzoate and isobutyl 4-chlorobenzoate were designed and synthesized. Crystal structure and 1H-1H NOESY experiments demonstrate that the oligomers adopt stable helical conformation, which are induced by C5-H...X-C (X = F, Cl) intramolecular hydrogen bonding between triazole protons and halogen atoms. The stabilities of the folded conformations are confirmed by DFT calculations, which show that each C5-H...F-C planar interaction lowers the energy by ～3 kcal mol-1 on average, and by ～1 kcal mol-1 when C5-H...Cl-C bridges are formed. The hydrogen-bonding networks are disrupted in competitive hydrogen-bonding media such as DMSO, generating the unfolded oligomers.
