Protonenresonanzspektren von Oximen aromatischer Aldehyde

Abstract: The NMR.‐spectra of 9 pairs of isomeric benzaldoximes are discussed. Syn‐anti structural assignment is possible using chemical shift data.

“…1 ppm at lower field (in DMSO) than that of the Z isomer. This is consistent with literature data on oximes 22 and O-alkyloximes. 23 The Z and E diastereoisomers are interconvertible at room temperature, the equilibrium ratio and kinetics depending on the solvent, light, and pH.…”

“…0.49 and 0.43 ppm, respectively. Although, δ C7 for both E and Z ring-substituted benzaldoximes correlates well with the σ constants, 29 no linear relationship between the shift of H7 and NOH, and σ R o values was found for the compounds studied.…”

“…The shift difference of Δδ = 0.67 ppm is characteristic for the two isomers. 41 Of the signals in absorption, benzene 13 at δ = 7.37 ppm has the highest intensity. It is generated by the decarboxylation of benzoyloxyl radical 6 to phenyl radical 7 and followed by hydrogen transfer from iminyl radical 5, the most likely hydrogen donor (see Scheme 3).…”
