Abstract: Product analysis studies of the hydrolysis of [NP (OCH2CF3) 2] 3 in basic aqueous methanol revealed a nongeminal pathway for the removal of trifluoroethoxy groups from phosphorus. Kinetic studies of the removal of the first fluoroalkoxy group from [NP (OCHzCF&13,[NP (OCHZCZF~)~ I~,[NP (OCH2C3F& [NP (OCH2CF3) &, and [NP (OCHZC, F~) ZI~ in basic 25 aqueous diglyme showed that, for cyclic trimers, the ease of ligand ...
