electrochemically-assisted synthesis of (hetero)arylphosphonates from (hetero)arylhalides and dimethyl phosphite is described. Very mild and simple conditions are employed as the cross-coupling is carried out in galvanostatic mode, in an undivided cell at room temperature, using NiBr2bpy as the easily available pre-catalyst and acetonitrile as the solvent. In addition, both aryl bromides and iodides can be used

Abstract Treatment of a novel polymer‐supported α‐diethoxyphosphoryl methyl selenide with LDA followed by alkylation and oxidative deselenation efficiently afforded diethyl trans‐1‐alkenephosphonates in good yields and purities.

Microwave-assisted reaction of dimethyl H-phosphonate with cyclohexene-, 1,2-butene-, and 1,2-decene oxides furnishes 8, 5, and 17 compounds, respectively. The probable mechanism of the formation of the various compounds via free radical reactions and their GC-MS characterization are presented in this article.
