Coupling reactions of alpha-bromocarboxylate with non-aromatic N-heterocycles.
The conditions for the C-N bond forming reaction (C-N coupling reaction) between alpha-bromocarboxylate and nitrogen-containing non-aromatic heterocyclic rings under heterogeneous copper(I) oxide catalysis are investigated in this paper. All the generated compounds were fully characterized by IR, NMR and MS spectroscopy. Ab initio/DFT calculations of partial charges on nitrogen atoms in all the discussed heterocycles and on C((2)) of carboxylate under applied conditions were predicted. These in silico results correlate relatively with the experimental observations.
