Notes:
The 31P—31P and 13C—31P coupling constants in 1,6-diphosphatriptycene have been obtained from analysis of its proton decoupled 13C n.m.r. spectra. More accurate data, however, resulted from simultaneous analysis of the proton decoupled 13C spectra and 31P(13C) satellite spectra. The 13C—31P couplings are strongly influenced by the proximity and orientation of the phosphorus lone pair electrons. The first 31P—31P coupling in an aromatic diphosphine is reported.
