The dilithiation procedure is the same as that reported previously for a range of other primary phosphines, see: K. Niediek, B. Neumüller, Z. Anorg. Allg. Chem. 1993, 885, 619. Whether the reaction of PhPH 2 with nBuLi produces a genuine dilithiate could not be ascertained by NMR spectroscopy due to the low solubility of the product. Attempts to prepare 1 by stepwise reaction of MeAlCl2 with PhPH2 followed by reaction with nBuLi failed. The presence of 2 equivalents of nBuLi in the reaction mixture prior to reaction with MeAlCl 2 is necessary to prevent an alternative pathway involving P-P bond formation

The ideal saturation-recovery curves were made to approximate actual saturation-recovery curves by the addition of 0.5% noise noise having a standard deviation equal to 0.5% intensity of the most intense point in the curve, and the inverse Laplace transform of the noisy curves were then taken. The inverse Laplace transform examined 120 time values logarithmically distributed between 0.01 s and 300 s. This process was repeated 100 times to investigate the reliability of the inverse Laplace transform. For the inverse Laplace transform for the curves with T1, 10s, all fits found the correct maximum but the standard deviation curve indicates that the greatest variation among the 100 fits performed occurs in the linewidth of the peak fit. Noise, therefore, often appears in the inverse Laplace transform as a broadened peak. It may also appear as a low-intensity component with T1 at either the high or the low end of the range searched over in the inverse
