Angewandte Chemie, EarlyView.A series of oxoiron(IV) complexes was synthesized to determine the impact of electronically tuned aromatic substitution in the secondary sphere of the ligand. Despite possessing identical electronic properties, they show significant differences in C─H oxidation reactions.

Heterocycle Grafted Monomers And Related Polymers And Hybrid Inorganic-organic Polymer Membranes
, 2005 Polymers, polymer precursors, and other materials are described, having at least one heterocycle and being useful for fabrication of proton-exchange membranes (PEMs). In representative examples, the heterocycle is a fluorinated imidazole ring.

Angewandte Chemie, EarlyView.By employing a sterically bulky monocoordinate bismuthinidene, the synthesis and characterization of the first examples of an unsupported iminobismuthane and tetraazabismole was achieved via reactions with organic azides. The corresponding amines could be accessed by reduction, leading to the regeneration of the Bi(I) compound. Hence, we also highlight

Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)
Angewandte Chemie, EarlyView.Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

The Synthesis of the first six-membered true heterocycle
, 2001 The synthesis and X-Ray structure of the first six membered non-ionic genuine heterocycle is reported. The non-planar ring is formed by Cu, O, C, N, P, and 5 and its conformation is described as pseudo boat.

Double Reduction of Ph3B to a Dianionic Borane With a Powerful SrI Intermediate
Angewandte Chemie, EarlyView.Although dianionic boranes follow the octet rule and are isoelectronic to carbanions or amines, the high electron density combined with the electropositive nature of the B center make them highly unstable species. In this study, we present synthesis and full characterization of a complex in which Ph3B2− is sandwiched between two Sr2+ ions and describe ...

Angewandte Chemie, EarlyView.Catalyst‐controlled nitrene transfer unlocks divergent reactivity of bicyclo[1.1.0]butanes. Rhodium catalysis promotes selective strain‐release amination to access cyclobutene and cyclobutane amino‐acid scaffolds, whereas visible‐light photocatalysis redirects nitrene reactivity toward double amination and skeletal remodeling, providing a complementary

Synthesis and Properties of the First [Au(dien)(N-heterocycle)]3+ Compounds
, 2016 Novel AuIII(dien)(N-heterocycle) compounds, including the first AuIIIN3(N-purine) examples, are reported. The acidity of the dien ligand is affected by the nature of the fourth ligand as a leaving group. The metal center of [Au(dien)(N-heterocycle)]3+

Redshifting TADF Emission With a Bora‐Triptycene Lewis Acid
Angewandte Chemie, EarlyView.Bathochromic emission shifting of donor–acceptor and multi‐resonant TADF emitters is achieved by adduct formation with a thia‐bora‐triptycene Lewis acid. TADF properties are retained on adduct formation whilst delivering > 100 nm redshift of the emission.
