Discussion The probable chemical transformations of PNDP are depicted in Scheme 11. PNDP (1) is subject to nucleophilic attack by all three available nucleophiles, if present: OH-, OBu-, and IBA. The major product formed in all cases is DPP (2) which, along with the second major product, PNPP (3), are stable to any further attack. BDPP (4), formed only in the CTAB microemulsion, does undergo further hydrolysis which was already discussed. ...
