Hallo friends
I have gone through a patent CN101875004A the inventor had attached iminodiacetonitrile to a chloromethlated polymer bead and described chelating ion exchange resin contain the copolymer of the styrene-divinylbenzene of formula (I) and formula (II)
Can any body help me mechanism of the proposed structure. The nitrogen of imino group of diacetonitrile is rearranged to convert NH2C[CH2-C(NH2)(NOH)]2 attached to benzene group of polymer.
Dear Balakrushna Padhi, please find the reaction path in page 2 of the following free access Chinese paper. My Regards

After all got a shared paper the structure as attached file is it correct?
No it is not the one you mentioned in the question, but this is another further modification of the dinitrile moiety. According to your query, the structure you are looking for is the one after the second arrow in the paper I attached.
The structure you showed is a (di)amidoxime, it is obtained after reacting the (di)nitrile with hydroxylamine (NH2OH).
