Polymerisation of Styrene using Pincer Type Amine Functionalized Azo Aromatic Complexes of Co(II) as Catalysts

In this present report, three mononuclear azo-aromatic complexes of Co(II), 1-3, and an imine-based Co(II) complex, 4, were synthesized through a reaction of respective amine-functionalized pincer-like ligands, HL1-4, with CoCl2.6H2O...

Aromatic interactions in Glycochemistry: from molecular recognition to catalysis

: Aromatic platforms are ubiquitous recognition motifs occurring in protein carbohydrate binding domains (CBDs), RNA receptors and enzymes. They stabilize the glycoside/receptor complexes by participating in stacking CH/ interactions with either the - or - face of the corresponding pyranose units. In addition, the role played by aromatic units in the stabilization of glycoside cationic transition states has started being recognized in recent years. Extensive studies carried out during the last decade have allowed to dissect the main contributing forces that stabilize the carbohydrate/aromatic complexes, while helping delineate not only the standing relationship between the glycoside/aromatic chemical structures and the strength of this interaction, but also their potential influence on glycoside reactivity.

Unraveling the Stability of Cyclobutadiene Complexes using Aromaticity Markers

Cyclobutadiene (CBD) is the paradigmatic antiaromatic molecule but is known to form highly stable aromatic complexes, e.g. CBD-Fe(CO)3. This intriguing reversal of aromaticity from antiaromatic to aromatic region during complexation...

Synthesis of stable polymetalated aromatic complexes through metal–macrocycle capsule-triggered cyclization

A dynamic coordination capsule derived from coordination-driven molecular folding of a flexible macrocyclic ligand was applied to trigger cyclization reactions and encapsulate unprecedented polysilver complexes of four different heteroaromatics.
