Angewandte Chemie, EarlyView.The luminescence of a heterometallic d‐s {Cu2I2Na2} phosphane‐phosphinate aggregate is regulated by an interplay of Na+–π/I– contacts and reversible coordination of oxygen‐containing organic molecules to Na ions. Structural variations caused by the incoming guest lead to a wide and selective variation of the emission color and illustrate a new approach

Angewandte Chemie, EarlyView.Hydride addition to coinage‐metal diphosphine–borane complexes gives unprecedented Cu(I), Ag(I), and Au(I) hydridoborates featuring agostic σ(B–H)→M interactions. While, Cu and Ag derivatives are inert toward CO2, the Au analogue reversibly fixes CO2 and catalyzes its hydroboration as well as formic acid dehydrogenation through a cooperative B─H─Au ...

Flavin Catalysts in Organic Synthesis
Angewandte Chemie, EarlyView.Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

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.
