Light without fright: A synthetic route to fluorescent primary phosphanes (RPH2) that are resistant to air oxidation both in the solid state and in chloroform solution is described. These versatile precursors undergo hydrophosphination to give tripodal ligands and subsequently fluorescent transition-metal complexes.
