Webchemists. Occasionally, the addition of H-phosphonates to activated unsaturated systems is also referred as the Pudovik reaction. 11 The most important feature of H-phosphonates is that two tautomeric forms are possible in this case - phosphonate (A) and phosphite (B). 7,10,12 P O RO OR H P RO OR OH phosphonate form
Webphosphonate, phosphonate, or phosphate functional group is limited by their inadequate membrane permeation and oral absorption. Phosphonate, phosphinate, and phosphate groups carry one or two negative charges at physio-logical pH values making them very polar (Figure 1).
