Abstract

Due to the rigid structure of 1,3,5-triaza-7-phosphaadamantane (PTA), its P-31 chemical shift solely depends on non-covalent interactions in which the molecule is involved. The maximum range of change caused by the most common of these, hydrogen bonding, is only 6 ppm, because the active site is one of the PTA nitrogen atoms. In contrast, when the PTA phosphorus atom is coordinated to a metal, ...
