Indeno[2,1‐c]fluoren Quasi[8]circulene mittels intramolekularer Cyclisierung

Angewandte Chemie, EarlyView.
Eine neue Klasse gewölbter, chiraler polyzyklischer aromatischer Kohlenwasserstoffe entsteht durch die Fusion von Indeno[2,1‐c]fluoren‐ und Quasi[8]circulen‐Motiven. Diese redoxaktiven, antiaromatischen Strukturen bieten eine hohe synthetische Vielseitigkeit, einstellbare Eigenschaften und modulare Funktionalitäten für organische Elektronik und ...

A Homobimetallic Frustrated Lewis Pair Cobalt Catalyst for the Methanolysis of Hydrosilanes

Angewandte Chemie, EarlyView.
The bimetallic Co(I)/Co(–I) complex [Co(CO)2(κ3‐P,N,P‐PNHP)][Co(CO)4] shows excellent activities in the methanolysis of hydrosilanes, reaching TOF values of ca. 50 000 h−1. This behavior can be ascribed to the presence of the [Co(CO)4]– anion, which allows for a frustrated Lewis pair mechanism, resulting in a low energy pathway for the heterolytic ...

Flexibility‐Aided Orientational Self‐Sorting and Transformations of Bioactive Homochiral Cuboctahedron Pd12L16

Angewandte Chemie, EarlyView.
Mimicking concave morphologies found in nature, we have introduced flexible, unsymmetric, tridentate ligand (L) which undergoes coordination self‐assembly into highly organized chiral Pd6L8 or Pd12L16 cages that can undergo interspecific transformations. The cages, being based on natural amphiphilic transport molecules, mediate high cellular uptake and

Dendritic Pillar[6]Arenes with Fixed Planar Chirality for Stereoselective Inclusions in Water: A Case of Facile Differentiation of Cocaine Adulterants, Levamisole and Dexamisole

Angewandte Chemie, EarlyView.
Dendritic pillar[6]arenes encompass a new class of cavitands with planar chirality, unique binding pockets, and great water solubility. These easily accessible hosts permit differentiating racemic dexamisole from levamisole as known cocaine adulterants.
