Abstract
NMR properties of 1,8-diphosphanaphthalenes with prerequisites for strong through-space interaction were studied. The exceptional magnitude of (4)J(PP) 246 Hz was found in Nap[P(NMe2)(2)][P(OMe)(NMe2)] (Nap = naphthalene-1,8-diyl). The P-III, P-V mixed valence systems Nap[P(E)(OMe)(2)][P(OMe)(2)] (E = O, S, Se) show much lower magnitudes of through-space interaction than expected.
