摘要: The 31P31P and 13C31P 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 simultaneous the spectra 31P(13C) satellite couplings are strongly influenced by proximity orientation phosphorus lone pair electrons. first an aromatic diphosphine is reported.
