34119969-3	2021	Herein, we confirmed that Co(II)/PAA reaction enables the generation of Co(IV) at acidic conditions based on multiple lines of evidences, including methyl phenyl sulfoxide (PMSO)-based probe experiments, 18O isotope-labeling technique, and in situ Raman spectroscopy.	methyl phenyl sulfoxide	148-171	mitochondrially encoded cytochrome c oxidase II	Homo sapiens	26-32	
33225681-2	2020	However, in this study, it was surprisingly found that methyl phenyl sulfoxide (PMSO) was readily oxidized to the corresponding sulfone (PMSO2) with a transformation ratio of ~100% under acidic conditions, which strongly implied the generation of high-valent cobalt-oxo species [Co(IV)] instead of SO4 - in the Co(II)/PMS process.	methyl phenyl sulfoxide	55-78	mitochondrially encoded cytochrome c oxidase II	Homo sapiens	311-317
