Reactions of Imidoyl Isoselenocyanates with Aromatic 2-Amino- N-heterocycles and 1-Methylimidazole
The reaction of N-phenylimidoyl isoselenocyanates 1 with 2-amino-1,3-thiazoles 10 in acetone proceeded smoothly at room temperature to give 4H-1,3-thiazolo[3,2-a] [1,3,5]triazine-4-selones 13 in fair yields (Scheme 2). Under the same conditions, 1 and 2-amino-3-methylpyridine (11) underwent an addition reaction, followed by a spontaneous oxidation, to yield the 3H-4l4-[1,2,4]selenadiazolo[1’,5’...
متن کاملCoupling Reactions of α-Bromocarboxylate with Non-Aromatic N-Heterocycles
The conditions for the C-N bond forming reaction (C-N coupling reaction) between α-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 dis...
متن کاملCrystal structure of bis(1-methyl-1H-imidazole-κN 3)(5,10,15,20-tetraphenylporphyrinato-κ4 N)iron(II)–1-methyl-1H-imidazole (1/2)
The title compound, [Fe(C44H28N4)(C4H6N2)2]·2C4H6N2, is a six-coordinate Fe(II)-porphyrinate complex with the metal located on a center of inversion and coordinated by two axial 1-methyl-imidazole ligands; the complex crystallizes as a 1-methyl-imidazole disolvate. The 1-methyl-imidazole group bonded to the Fe(II) atom [occupancy ratio 0.789 (4):0.211 (4)] and the unbound 1-methyl-imidazole mol...
متن کاملCrystal structures of the two salts 2-methyl-1H-imidazol-3-ium nitrate–2-methyl-1H-imidazole (1/1) and 2-methyl-1H-imidazol-3-ium nitrate
The title salts, C4H7N2 (+)·NO3 (-)·C4H6N2, (I), and C4H7N2 (+)·NO3 (-), (II), were obtained from solutions containing 2-methyl-imidazole and nitric acid in different concentrations. In the crystal structure of salt (I), one of the -NH H atoms of the imidazole ring shows half-occupancy, hence only every second mol-ecule is in its cationic form. The nitrate anion in this structure lies on a twof...
متن کامل1-Methyl-5-nitro-1H-imidazole
In the title compound, C(4)H(5)N(3)O(2), the nitro group is twisted with respect to the imidazole ring by a dihedral angle of 5.60 (2)°. Weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonding is present in the crystal structure.
