Abstract: 5‐Methylcytidine (m5C) and 5‐methyluridine (m5U) are highly abundant post‐transcriptionally modified nucleotides that are observed in various natural RNAs. Such nucleotides were labeled through a chemical approach, as both underwent oxidation at the C5=C6 double bond,…

Abstract: Summary Mononuclear metal-peroxo species are invoked as the key intermediates in metalloenzymatic or synthetic catalysis. However, either transience or sluggishness reactivity of synthetic analogs of metal-peroxo species impedes our understanding of oxygen activation mechanism. Herein,…
