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 … WebJan 1, 2024 · Phosphonate.
