Imidazole and its derivatives are assigned as an exclusive and multifaceted skeleton because of having a variety of applications in medicinal and synthetic organic chemistry as well as in the field of industrial chemistry. For these perspectives, various elegant methods for imidazoles and its derivatives have been developing over the last years using different types of catalyst to improve selectivity, purity, and yield of the product. Thus, we have reviewed various synthetic routes for the formation of imidazoles and their applications from 2014 to 2016.

Piperidinium hydrogen sulfate is used as a very important new catalyst for the synthesis of the biologically active compounds from a series of multi‐substituted imidazole components by the simple reaction of benzyl with different aromatic aldehydes, ammonium acetate, and phenethylamine or butylamine as amine derivatives. The key merits of this method are very shorter reaction times, excellent yield, and ease of stabilization. Furthermore, the produced products can be purified by a non‐chromatographic technique, and the catalyst is reusable. All of these new synthesized components have been characterized and checked from spectral data: IR, 1H‐NMR, and 13C‐NMR spectra and elemental analyses.

“…Furthermore, the electronic properties of linear aromatic system can be tuned by modifying the functional groups attached to the aromatic rings with a fluoroionophore bearing a carbon center of suitable electrophilicity for the selective interaction with cyanide ,,,. Keeping these perspective in mind we herein, developed a new class of simple organic molecular scaffold, probe 2 and 3 to detect cyanide as well gaseous hydrogen cyanide (HCN) through a reaction base chemodosimeter approach.…”

The present work describes design and synthesis of a biphenylaldimine derivative, probe 2 as an efficient molecular scaffold. The probe 2 showed good photophysical behavior and upon interaction with anions and gases showed high selectivity and sensitivity for CNanion and HCN gas through a reaction based chemodosimeter approach with limit of detection 24 ppb and 7 ppm, respectively. The change in optical behavior of the probe is attributed to intramolecular charge transfer (ICT) mechanism. Probe 2 displayed enhanced emission, "turn-on" due to the formation of a new biphenyl oxazole derivative 4 in the medium along with change in color of the medium which was sensitive to the naked-eyes. The mechanism of interaction between probe and cyanide anion have been confirmed by the 1 H NMR, 13 C NMR and HRMS spectral data analysis. The molecular probe 2 has been successfully utilized to detect cyanide (CN -) and HCN gas in solution and on test paper strips.
