A high-pressure high-resolution NMR study for 2,11-dithiaI3.3.n]paracyclophanes (n=1,2) revealed that the Hxprotons of ring A shift notably to high field, whereas the Ha,bprotons of ring B move to low field. Reduction of the partial volumes under high pressure, being effected by changes in the dihedral angles, is responsible for the chemical shift changes. |
