Rapid RNA strand scission following C2'-hydrogen atom abstraction. [PDF]
C2'-Nucleotide radicals have been proposed as key intermediates in direct strand break formation in RNA exposed to ionizing radiation. Uridin-2'-yl radical (1) was independently generated in single- and double-stranded RNA via photolysis of a ketone precursor.

DNA double strand cleavage via interstrand hydrogen atom abstraction. [PDF]
Double strand breaks (DSBs) are the most deleterious form of DNA damage. Natural products that produce them are potent cytotoxic agents. Designing molecules that produce DSBs via a single chemical event is challenging. We determined that formation of a C4'-nucleotide radical in duplex DNA under aerobic conditions gives rise to a DSB.

Catalytic Ammonia Oxidation to Dinitrogen by Hydrogen Atom Abstraction
AbstractCatalysts for the oxidation of NH3 are critical for the utilization of NH3 as a large‐scale energy carrier. Molecular catalysts capable of oxidizing NH3 to N2 are rare. This report describes the use of [Cp*Ru(PtBu2NPh2)(15NH3)][BArF4], (PtBu2NPh2=1,5‐di(phenylaza)‐3,7‐di(tert‐butylphospha)cyclooctane; ArF=3,5‐(CF3)2C6H3), to catalytically ...
