Abstract

Abstract We have developed a new method of N-nitrosation of various secondary and tertiary amines, amides and ureas using a mixture of tin (IV) chloride and sodium nitrate. This method leads to a selective, high-yielding and mild heterogeneous N-nitrosation by in situ generation of nitrosyl chloride (NOCl). The reaction can be carried out in several different solvents such as chloroform, dichloromethane, ethers, ethyl acetate and alcohols, ...
