Sodium ions can be used as efficient chemical ionization agents in electrospray mass spectrometry of a wide variety of neutral metal bipyridine complexes. This ionization method was successfully permitted the identification of a neutral metal complex generated during the photochemical ligand substitution reaction: [Re(bpy)(CO)3{P(OEt)3}] + +Cl -® Re(bpy)(CO)2{P(OEt)3}Cl+CO by sodium adduct formation to produce an electrospray-active species [Re(bpy)(CO)2{P(OEt)3}Cl+Na] + .
