The present work describes the excellent catalytic activity of copper(II) oxide nanoparticles (NPs) towards N-arylation of aniline and imidazole at room temperature. The copper(II)oxide NPs were synthesized by a thermal refluxing technique and characterized by FT-IR spectroscopy; powder XRD, SEM, EDX, TEM, TGA, XPS, BET surface area analysis, and particle size analysis. The size of the NPs was found to be around 12 nm having a surface area of 164.180 m 2 g -1.The catalytic system was also found to be recyclable and could be reused in subsequent catalytic runs without a significant loss of activity.

A chemosensor system has been developed for rapid and selective detection of cyanide. The sensory molecules have the donor-acceptor type of structure and are designed by tuning the LUMO level or their reactivity towards cyanide. This sensory system is able to selectively distinguish cyanide among fluoride and many other anions at micromolar concentrations and instantly detect cyanide at ambient temperatures with a detection limit down to 1.0 M. Multiple sensory signals are available and can be used for both qualitative monitoring and quantitative determination of cyanide, including high-contrast visual color change, fluorescence quenching and enhancement in the visible and near-infrared spectral regions.
