Enhancement of the basicity of the amino group in (8-dialkylamino-naphth-1-yl)-diphenylphosphines diverts protonation from the P to the N atom. Thus the cation 8-Et2N+(H)-C 10H6-PPh2 becomes available whose 1H and 31P NMR spectra provide arguments against dative N→P interactions in the phosphines and their quaternary phosphonium salts. Likewise, the X-ray structure of 8-Et2N-C10H6-PPh 2 does not indicate such interactions.
