A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1608-26-0, Name is Tris(dimethylamino)phosphine

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.
