Nano- gama -Alumina supported SnCl۴: A novel nitrosating agent for the chemoselective N-nitrosation of secondary amines under grinding andsolvent-free conditions

چکیده مقاله

N-Nitrosamine compounds are present in water, soil and air. Due to the variety applications of these compounds in the various industries as insecticides, pesticides, cosmetics, antioxidants, lubricant additives and N=O agents transmitter. In recent years, the researchers focused on the biological terms of N-nitrosamines. To date, number of variety reagents such as nitrous acid (HNO2), dinitrogentrioxide (N2O3), nitrosonioum salts and alkyl nitrites (RNO2) have been used for the nitrosation reactions. The most common of these reagents is nitrous acid.
