Beyond the Oxo‐Wall: Synthesis and Reactivity of a Six‐Coordinate Formally CoIV‐Oxo Complex

Angewandte Chemie, EarlyView.
We present the first example of a six‐coordinate formally Co(IV)‐oxo complex, [Co(TQA)(O)(OH)]+ (1), which exists as an admixture of CoIV‐oxo and CoIII‐oxyl resonance structures. Complex 1 is capable of performing oxygen atom transfer reactions and abstracting moderately strong hydrogen atoms at rates faster than other characterized CoIV‐oxo compounds.

3D Liquid Crystal Framework Enclosing Dual Compartments

Angewandte Chemie, EarlyView.
A new type of liquid crystal phase is reported, having the conjugated rod‐like molecular cores form a 3D framework of elongated octahedral cages filled alternatively with alkyl and fluoroalkyl pendant chains. The cages are held together by flexible H‐bonding hinges, making them adaptable to thermal expansion and stable in a wide temperature range.

Dyotropic Rearrangement of Hypervalent Iodine Species: Migrative Heterofunctionalization of Quaternary Carbons

Angewandte Chemie, EarlyView.
1,2‐Aryl migration involving in situ‐generated alkyl iodine(III) species proceeds through a previously unrecognized 1,2‐C/I(III) dyotropic rearrangement. Migratory aryl fluorination, acetoxylation, and alkoxylation of 2‐alkyl‐2‐aryl‐3‐iodopropanoates provide α‐heterofunctionalized products, accompanied by aryl migration from the α‐ to the β‐position ...

Substrate‐Dependent Crosslinking by the Cytochrome P450 From Aminopyruvatide Biosynthesis

Angewandte Chemie, EarlyView.
Substitutions in the aminopyruvatide precursor peptide altered the C─C linkage formed from a YLY motif by the P450 ApyO to a N─C linkage in a WLY motif. Moreover, constitutional isomers crosslinked by C─C and C─O linkages were formed from YYY or YWY motifs. ABSTRACT Cytochrome P450s catalyze an array of reactions including crosslinking of aromatic side
