Abstract Air-stable, fluorescentprimary phosphines have been prepared on a multigram scale. The two key synthetic steps are an optimized palladium-catalyzed phosphonylation of aryl bromides and a boron–carbon bond formation reaction. The method provides a valuable synthetic route to novel fluorescent derivatives via a key phosphonate intermediate. Air-stable, fluorescentprimary phosphines have been

The syntheses of highly fluorescent analogues of PPh3 and PhPCy2 based on the Bodipy chromophore are described. The ligands have been incorporated into two- to four-coordinate group 11 metal complexes. The synthesis, characterisation and photophysicalproperties of the novel ligands and their metal complexes are reported; many of these compounds have also been characterised by single-crystal X-ray
