Various α-hydrazidophosphonates have been easily prepared on the basis of the nucleophilic addition of diphenyl phosphite to reactive, preformed N-acylhydrazones and a three-component (aldehydes, N-benzoylhydrazide and diphenyl phosphite) coupling reaction through a non-catalyzed process. An unprecedented and promising enantioselective example of this reaction is also reported.

properties of hydrazones and phosphonyl species, and their coordination properties remains unknown. The coordination chemistry of these ligands towards group11metals has been studied. A series of novel gold(I), silver(I) and copper(I) complexes with α-hydrazidophosphonate ligands have been prepared and characterised. The coordination geometries obtained vary from the linear to the trigonal planar for gold(I)
