The oxidation of 1,4-dihydropyridines has been carried out using catalytic quantity of transition metal nitrates supported on silica gel under IR irradiation. The C-4 de-alkylation is found to be minimal due to milder reaction conditions. The new protocol has been found to be economic and environment friendly. © 2011 Iranian Chemical Society. Source

Benzimidazoles and benzothiazoles show significant and promising activities against various viruses such as HIV and HCMV-1. Their synthesis using cobalt nitrate and hydrogen peroxide in N,N-dimethylformamide has been presented in the following study. The cobalt nitrate/H 2O 2 appears to be a smooth and efficient reagent system for the synthesis of 2-aryl substituted benzimidazoles and benzothiazoles. Simple and convenient reaction procedures and shorter reaction times are the salient features of the presented route. Source

Juglans regia, the royal species from Junglandaceae family, well-known for its valuable medicinal uses is grown in the forests of Himalayas in India. It is a woody, deciduous and frost-tender tree. The root, stem bark, leaves, seeds, cotyledons and seed oil are useful to treat various health complaints including cancer in the folk medicines. Chemical analysis is carried out on the stem bark of the species to determine qualitatively and quantitatively the elements present in it. Different standard methods like Kjeldahl, Colorimetry, Flame photometry and Atomic absorption spectrophotometry (AAS) are used for the experiments. Results show considerable percentage of Iron, Nitrogen, Copper and traces of Zinc, Manganese and Potassium Phosphorous. Source
