摘要:

The complexes between phenols and N-tBocsarcosine N',N'-dimethylamide, N-tBoc-sarcosylsarcosine N',N'-dimethylamide or polysarcosine are investigated in dichloromethane by FT-IR spectrometry. In the two first sarcosine derivatives, complex formation occurs at the urethane and at the amide carbonyl groups. The lengthening of the peptide chain from n=2 to n=40 exerts only a weak influence on the stability constants.
