4. For (SCRN,SS)-2a: m.p. (dec) 204–206°C, [α]D20 −34.3 (c 1.5, MeOH). Anal. calcd: C, 56.18; H, 6.41; N, 7.86 for C25H32ClN3Pd·H2O. Found: C, 56.01; H, 6.14; N, 7.75. Diastereomeric purity (88% de) was determined by 1H NMR using the integral intensity of the Me groups of the NPri substituent.
5. The 1H NMR spectra of the starting mixture of dimer (SCRN)-1 and racemic Stien in a 1:4 molar ratio contains two sets of signals from the two diastereomers 2a,b in nearly a 1:1 ratio and the signals of free diamine. The absence of stereoselectivity in their complexation seems to be a result of the low efficiency of steric interactions between the benzylaminate palladacycle and the primary amino groups of the diamine (cf. findings of Leung et al.6); it is likely that the disruption of the agostic interaction iso-Pr…Pd in a polar medium may decrease the conformational stability and ability to chiral recognition of palladacycle as well.
