A mild and efficient method was developed for the copper-catalyzed additions of H-phosphonate diesters to boronic acids under the copper catalyst system Cu2O/1,10-phenanthroline. To the best of our knowledge this finding is the first example of a copper-catalyzed synthesis of aryl phosphonates from arylboronic acids and H-phosphonate dialkyl esters.

The synthesis and characterization of a new class of electron donor-acceptor substituted stilbenes hearing a phosphonate ester as the electron-withdrawing functionality is described. Phosphorylation of aromatic rings was accomplished using Ni-catalyzed Arbuzov reactions, while Pd-catalyzed Heck-type coupling reactions were employed to construct the stilbene derivatives. Through determination of an electro-optic coefficient (r33), it was demonstrated that the phosphonate ester group is effective as an electron-withdrawing group for stilbene-based second-order NLO materials.
