Popis: Quinone methides (QMs) are very important intermediates in chemistry. These species are most often generated in situ with metal oxidants and transition metal complexes. Here, tip-enhanced Raman spectroscopy (TERS) has been implemented to investigate the in situ oxidative generation of a QM species from alkylphenols facilitated by a transition metal complex. Using TERS, the metal oxidant-mediated transformation of a phenol species has been observed. The subsequent oxidative addition reaction of QM has also been identified based on distinct vibrational features, which have been assigned based on density functional theory (DFT). This study may establish TERS as a chemical detection tool for various QM-mediated reactions.
