Fig. 2.23 1 H NMR spectra of eleven 3 ground obtained by grinding of 3/CHCl 3 , 3/Py, 3/CH 2 Cl 2 ,
3/CH 2 Br 2 , 3/DMA, 3/AcH, 3/CH 3 CN, 3/DMF, 3/SPO, 3/racPO, and 3/acetone in CDCl 3 . Note
For 3 ground powders obtained from 3/CH 2 Br 2 , 3/DMA, and 3/DMF by mechanical stimulation, the
proton signals of residual solvents are observed in their 1 H NMR spectra. Considering high boiling
point of these solvents, this result indicates that slight amount of released solvents from the crystal
lattices remains around the 3 ground phases
