Abstract
Reaction intermediates of CO2-photofixation using [Re(bpy)(CO)3PPh3]+(bpy=2, 2′-bipyridine) have been studied by electrospray mass spectrometry. A triethanolamine (TEOA) complex, [Re(bpy)(CO)3(TEOA)]+, was detected for the first time as a key intermediate. Electrospray mass spectrometry was found quite useful for detecting and identifying unstable photoreaction intermediates of rhenium complexes.
