Benzimidazole ring is a useful synthon in medicinal chemistry and is a part of many biologically active compounds. This communication reports a mild and efficient approach for the synthesis of benzimidazole ring through oxidative cyclization of o-phenylenediamine and different aldehydes using dioxane dibromide, as a user-friendly reagent. This is a new, convenient and facile methodology for the synthesis of 2-substituted-1H-benzo[d]imidazoles.

In the present investigation, an attempt has been made to investigate the pollution status of domestic sewage near fort area at Udgir. The Study of Physico-chemical parameters viz. Temperature, pH, Electrical conductivity (EC), Total Dissolved Solids (TDS), Total hardness (TH), Dissolved Oxygen (DO), Sodium, Potassium, Sulphate and Phosphates were investigated. Result show considerable seasonal variation in physico-chemical parameters. Copyright © EM International.
