Ground‐ and Excited‐State Mixed Valency in a 4,4′‐Bipyridine‐Bridged Bimetallic Di‐Ruthenium Complex

European Journal of Inorganic Chemistry, EarlyView.
Photoinduced mixed‐valence interactions across a 4,4′‐bpy bridge were studied. MLCT excited states in the bimetallic complex are longer‐lived than in the monometallic reference, thanks to metal–metal electronic coupling and hole delocalization, but are still shorter than the nanosecond timescale relevant for diffusional reactivity.

Intramolecular Matere Bonds in Isostructural Rubidium (18‐Crown‐6) Pertechnetate and Perrhenate Dimers

European Journal of Inorganic Chemistry, EarlyView.
Two rubidium cations that are not fully encapsulated by 18‐crown‐6 are bridged by two pertechnetate units to form a dimer. These two pertechnetate units are nearly linearly aligned to each other to form Matere bonds (MaBs), a type of noncovalent σ‐hole interaction.

Mechanistic Paths for the Gold(I)‐Catalyzed Heteroannulation of Salicylic Amides With Apolar Alkynes Explored With Density Functional Theory Calculations

European Journal of Organic Chemistry, EarlyView.
A manifold of catalytic reaction paths can operate in the Au(I)‐catalyzed heteroannulation of salicylic amides and alkynes. However, a subtle initial nucleophilic advantage of N versus O and a kinetic bottleneck at an advanced stage of the mechanistic machinery seems to suffice for the reaction to run on a single path and with exquisite selectivity.

1,1‐Disubstituted Vinylbromides: Versatile Building Blocks for the Synthesis of Nitrogen‐Containing Heterocycles

European Journal of Organic Chemistry, EarlyView.
1,1‐Disubstituted vinylbromides are key intermediates for constructing nitrogen‐containing heterocycles. This review provides an overview of the synthetic applications of 1,1‐disubstituted vinylbromides and summarizes recent developments in reaction methodologies, mechanistic insights, and the structural diversity of N‐heterocyclic compounds accessible
