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.

Katalytischer Schwefelatomtransfer vermittelt durch einen Bis(disulfido)‐Titankomplex

Angewandte Chemie, EarlyView.
Mehrelektronentransformationen mit Titan sind aufgrund der limitierten Zugänglichkeit niedervalenter Vorstufen bislang nur unzureichend untersucht. Die Vier‐Elektronen‐Aktivierung von elementarem Schwefel durch einen Ti(IV)‐Komplex führt zu einem seltenen Bis(disulfido)‐Titankomplex, der die effiziente katalytische Synthese von Isothiocyanaten aus ...

Silicon‐Bridged Homocyclopentadienides: Metal‐Assisted Facile Ring Expansion of Cyclopentadienide by Transient Imino(Metallophosphino)Silylenes

Angewandte Chemie, EarlyView.
We demonstrate the facile aromatic C─C bond cleavage of cyclopentadienide mediated by transient imino(metallophosphino)silylenes, enabling the transformation of an aromatic system into a homoaromatic species. The steric bulk of the phosphino substituent, together with the weak interaction between the coinage metal and the cyclopentadienide ligand, are ...

A Mechanical sp2‐Jail for C60 Fullerene

Angewandte Chemie, EarlyView.
A rigid bisporphyrin receptor with an exceptionally compact 3D cavity functions as a molecular “mechanical jail”, tightly enclosing C60 fullerene. Near‐perfect shape complementarity affords ultrahigh binding affinity while imposing a large kinetic barrier for guest exchange, rendering encapsulation effectively irreversible under ambient conditions ...

Water, Alcohols, Amines, and Amides as Formal Hydrogen‐Atom‐Transfer Reagents Through Activation With Redox‐Active Lewis Acids

Angewandte Chemie, EarlyView.
Protic molecules containing strong O─H or N─H bonds typically resist hydrogen‐atom abstraction because of the high reactivity of the resulting heteroatom‐centered radicals. However, association of the protic molecules with redox‐active Lewis acids can provide powerful hydrogen‐atom donors or proton‐coupled‐electron‐transfer reagents.
