Phosphonane
Webnate diesters [O=PH(OR) 2] one should expect lower reactivity than for C-phosphonates, as electroneg- ativity of phosphorus and hydrogen are almost the same. Since the phosphorus center in H-phosphonate diesters is significantly more electrophilic than that in C-phosphonate diesters, there must be a mecha- nism that increases electron density at the … WebNational Center for Biotechnology Information

WebDiethylphosphite is the organophosphorus compound with the formula (C 2 H 5 O) 2 P (O)H. It is a popular reagent for generating other organophosphorus compounds, exploiting the high reactivity of the P-H bond. Diethylphosphite is a colorless liquid. [1] The molecule is tetrahedral . Synthesis and properties [ edit] 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). This high polarity is the basis for many deficiencies in terms of drug ...

WebThe hydrolysis of phosphinate-, phosphonate-, and phosphoric esters is an important synthetic step; however, its realization is more difficult than that of carboxylic acid esters [59,60]. In most cases, the acid-catalyzed hydrolysis is applied, which means boiling the respective P-ester in aqueous hydrochloric acid.
