Geometrical isomers of $\lambda$3-diazadiphosphetidines show large differences in their 31P chem. shifts. Trifluoroethoxylation of cis-$(PhNPCl)_2$ gives only the low-field isomer initially, for which the crystal structure is detd. The alkoxy groups are trans to each other. On standing in soln., trans-$[PhNP(OCH_2CF_3)]2 $transforms slowly and almost completely into its cis analog with a high-field 31P chem. shift.
