dcterms:description
Homologous series of dihydroxamic acids [HONHCO(CH2)nCONHOH with n = 0, 1, 2, 3, 4 and 6] were prepared and trimethylsilylated [1(n) and 2(n)]. The solution NMR spectra (1H, 13C, 15N) of 1(n) show that the hydroxamic and groups assume Z-Z and Z-E combinations of conformers. An exception is oxalodihydroxamic acid, which assumes only one combination. 13C cross-polarization magic angle spinning reproduces the solution chemical shift in this compound and indicates the Z-Z combinanation as determined earlier by x-ray diffraction.
