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. WebSep 21, 2024 · A novel microporous two-dimensional (2D) Ni-based phosphonate metal-organic framework (MOF; denoted as IEF-13) has been successfully synthesized by a simple and green hydrothermal method and fully characterized using a combination of experimental and computational techniques.
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 …
