B. Korybutdaszkiewicz, METAL-ION PROMOTED NUCLEOPHILIC-SUBSTITUTION OF HYDROGEN IN CHELATED MACROCYCLIC ALPHA-DI-IMINE, Journal of coordination chemistry, 27(1-3), 1992, pp. 219-221
Base-catalyzed addition of nitromethane to the Ni(II) co-ordinated alp
ha-di-imine, followed by elimination of HNO2 and rearrangement of the
double bond formed, leads to the methyl substituted product, i.e. the
nucleophilic substitution of the imine hydrogens occurred.
