Nonclassical oxygen atom transfer reactions of an eight-coordinate dioxomolybdenum(vi) complex

Eight-coordinate MoO2(DOPOQ)2 can donate two oxygen atoms to substrates such as phosphines in a four-electron nonclassical oxygen atom transfer reaction.

Intercepting a Transient Non-Hemic Pyridine N-Oxide Fe(III) Species Involved in Oxygen Atom Transfer Reactions

In the context of bioinspired OAT catalysis, we developed a tetradentate dipyrrinpyridine ligand, a hybrid of hemic and non-hemic models. The catalytic activity of the iron(III) derivative was investigated in...

Mechanistic insight into oxygen atom transfer reactions by mononuclear manganese(iv)–oxo adducts

Rate enhancements in sulfoxidation reactions are often associated with a change in mechanism. Kinetic studies of sulfoxidation reactions by a series of MnIV–oxo complexes reveal large rate changes while retaining an oxygen-atom transfer mechanism.

Corrole photochemistry

The rapid expansion of photoredox catalysis and artificial photosynthesis has garnered renewed interest in the field of photochemistry. While porphyrins have been widely utilized for a variety of photochemical applications, corrole photochemistry remains underexplored, despite an exponential growth in corrole chemistry. Indeed, less than 4% of all corrole-related publications have studied the photochemistry of these molecules. Since corroles exhibit chemical properties that are distinct from porphyrins and related macrocycles, it is likely that this divergence would also be observed in their photochemical properties. This review provides a comprehensive summary of the extant corrole photochemistry literature. Corroles primarily serve as photosensitizers that transfer energy or an electron to molecular oxygen to form singlet oxygen or superoxide, respectively. While both of these reactive oxygen species can be used to drive chemical reactions, they can also be exploited for photodynamic therapy to treat cancer and other diseases. Although direct photochemical activation of metal–ligand bonds has been less explored, corroles mediate a variety of transformations, particularly oxygen atom transfer reactions. Together, these examples illustrate the diversity of corrole photochemistry and suggest that there are many additional applications yet to be discovered.
