Complete multinuclear magnetic resonance analysis of heterophospholanes and their sulfur, selenium and borane adducts

1H, 11B, 13C, 15N, 31P and 77Se NMR spectra were obtained for 1,3-(dioxa, oxaza or diaza)-2-phospholanes and their sulfur, selenium and borane adducts. The relative sign of the 3J(1H, 31P)/2/(13C, 31P) coupling constants was found to be positive in the sulfur and selenium adducts for the methylene and methyl groups. Conversely, for the compound with a phosphorus lone pair and in the borane adducts this sign changes for the methylene groups. It was shown that the 31P NMR spectra recorded by the CPMG or INEPT-HEED pulse sequences can be used for observation of the 15N-31P coupling constants. In all the investigated compounds the spin-lattice relaxation of 31P is controlled by the spin-rotation mechanism. The dipole-dipole 31P-11B interactions can provide less than 20% of the relaxation rate in compounds containing the BH3 group. The transverse 31P relaxation is dominated by the scalar contribution.
