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

A series of vinylic and arylic phosphonates and phosphonic bis(diethylamides) were prepared by copper promoted substitution of the corresponding bromides. These Ï-electron conjugated phosphonates and phosphonic bis(diethylamides) were investigated to elucidate their optical and second harmonic generation (SHG) properties; it was found that diphenyl 2-(4-dimethylaminophenyl)ethenylphosphonate exhibited strong SHG activity, the efficiency being 13 times greater than that of urea.
