Ligand‐Controlled Chemoselectivity in the Rhodium‐Catalyzed Synthesis of Pentafulvenes via (2 + 2 + 1) Alkyne Cyclotrimerization

Angewandte Chemie, EarlyView.
Chemoselectivity Challenge: A precise catalyst design allows for chemoselectivity control over alkyne reactivity to yield pentafulvenes via (2 + 2 + 1) cyclotrimerization. Operative mechanism has been elucidated by means of stoichiometric and deuteration experiments, as well as DFT calculations.

Tailoring Tubular Supramolecular Polymers with Polar Lumens to Host Hydrophilic Dye Molecules

Angewandte Chemie, EarlyView.
A unique class of tubular polymer structures that are soluble in apolar organic solvents but are endowed with polar pores has been created through the rational design of the monomer units, which self‐assemble in amphiphilic cyclic entities that then stack into tubular architectures. These tailored assemblies are able to selectively host hydrophilic dye

Stepwise Acetylene Insertion and Ammonia Activation at a Digallene and Diindene

Angewandte Chemie, EarlyView.
The stepwise insertion of acetylene into the E═E bonds of digallenes and diindenes is reported. This leads to the selective formation of four‐ and six‐membered rings with 2π E2C2 and 4π E2C4 cores. The six‐membered cyclohexadiene analogues are Lewis‐acidic and can form stable, isolable adducts with ammonia, which—upon heating—undergo ammonolysis ...
