Abstract
Nano-kaolin-SO3H was prepared and used to synthesis of N-nitrosamines. The products were characterized by their spectral (IR and 1H NMR) data. N-nitrosamines can exist in two mesomeric forms but the reaction is quite regioselective and only one of mesomers is formed as a main product which can exist in two E and Z stereoisomers. In this paper, we have studied the mesomeric effect of N-nitrosamines which explained the diastereotopic nature of corresponding protons in symmetric N-nitrosamines and formation of two isomers in asymmetric N-nitrosamines.
