New reactive intermediates in organic chemistry

Research into reactive intermediates has historically been part of the work involved in product studies. In order to characterize a reactive intermediate, it had to be trapped. Using internal quenchers (molecular clocks) providing well-defined competing reactions, product studies can even yield accurate values for intermolecular quenching reactions of reactive intermediates. More recent techniques to characterise reactive intermediates include matrix isolation spectroscopy, laser flash photolysis, or specialised mass-spectrometric techniques.
