ATTEMPTED PREPARATION OF N-SUBSTITUTED DIPHENYLCYCLOPROPENEIMINE N-OXIDE
The reaction of diphenylcyclopropenone with several N-substituted hydroxylamine and primary amines are investigated. Most of these reactions led to ring opened or ring enlarged products, instead of the desired N-Oxide or imine. The reaction of cyclopropeneimine with peracid-another possible route to N-substituted cyclopropeneimine N-Oxide is studied. Most of the unexpected products are ide...
متن کاملCrystal structure of 1-methylimidazole 3-oxide monohydrate
1-Methylimidazole 3-N-oxide (NMI-O) crystallizes as a monohydrate, C4H6N2O·H2O, in the monoclinic space group P21 with Z' = 2 (mol-ecules A and B). The imidazole rings display a planar geometry (r.m.s. deviations = 0.0008 and 0.0002 Å) and are linked in the crystal structure into infinite zigzag strands of ⋯NMI-O(A)⋯OH2⋯NMI-O(B)⋯OH2⋯ units by O-H⋯O hydrogen bonds. These chains propagate along t...
متن کاملAqua(picolinato N-oxide-κ2 O 1,O 2)(pyridine-2,6-dicarboxylato-κ3 O,N,O′)iron(III) monohydrate
In the title compound, [Fe(C(6)H(4)NO(3))(C(7)H(3)NO(4))(H(2)O)]·H(2)O, the Fe(III) ion is coordinated by two O and one N atoms from a pyridine-2,6-dicarboxyl-ate ligand, by two O atoms from a picolinate N-oxide ligand and by one water O atom in a distorted octa-hedral geometry [Fe-O = 1.940 (3)-2.033 (3) Å and Fe-N = 2.057 (4) Å]. In the crystal structure, the coordinated and solvent water mol...
متن کاملThermochemical studies of N-methylpyrazole and N-methylimidazole.
The 351.1 nm photoelectron spectra of the N-methyl-5-pyrazolide anion and the N-methyl-5-imidazolide anion are reported. The photoelectron spectra of both isomers display extended vibrational progressions in the X2A' ground states of the corresponding radicals that are well reproduced by Franck-Condon simulations, based on the results of B3LYP/6-311++G(d,p) calculations. The electron affinities...
متن کاملDiaquabis(2-pyridylphosphonato N-oxide-κ2 O 1,O 2)cobalt(II)
In the title complex, [Co(C(5)H(5)NO(4)P)(2)(H(2)O)(2)], the Co(II) ion, which lies on a crystallographic inversion center, is coordin-ated by four O atoms from two bidentate 2-phospho-nato-pyridine N-oxide ligands and two O atoms from two water ligands in a slightly distorted octa-hedral environment. Mol-ecules are inter-linked by three O-H⋯O hydrogen bonds and one weak C-H⋯O inter-action, for...
