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.
