Abstract

The chem. shifts and coupling constants of a series of new asym. substituted 1,3,2-diazaphospholidine compounds, were determine Furthermore, the spin-lattice relaxation time T1 of 2-(diethylamino)-1-(p-methylbenzenesulfonyl)-3-(4',6'-dimethoxyl-s-triazi n-2-yl)-1,3,2-diazaphospholidine (I) was measured. The assignment of the 13C signals, which is hard to determine with other decoupling techniques, was based on the calculated dipolar relaxation time T1DD. The relationship between the coupling constant and the configuration was described.
