摘要:

The 220 MHz p.m.r. spectra of 4-(4′-nitrothiobenzoyl)-2,6-dimethylmorpholine (1) provide evidence for the progressive freezing of the librations of the thioamide group around the C(S)—Ph bond as the temperature is lowered. This is supported by spectral data on related compounds in which the aromatic and hetero-ring substituents are altered.
