Pd(II)‐Catalyzed Strategies for the β‐Arylation of α‐Amino Acids: An Overview

Chemistry – A European Journal, EarlyView.
The graphical abstract summarizes the review “Pd(II)‐Catalyzed Strategies for the β‐Arylation of α‐Amino Acids: An Overview”, highlighting representative Pd(II)‐catalyzed methods for the β‐arylation of α‐amino acids. Key mechanistic features, substrate diversity, and synthetic relevance of these transformations are showcased. Abstract Metal‐catalyzed C─

Carbon and Heteroatom Activation via N‐Heterocyclic Carbene‐Bound Dearomative Intermediates for Stereoselective Annulation Reactions

Chemistry – A European Journal, EarlyView.
Use of N‐heterocyclic carbenes (NHCs) to activate carbon and heteroatoms in aromatic compounds is reviewed based on key dearomative NHC‐bound intermediates, i.e., ortho‐quinodimethanes (o‐QDMs), ortho‐quinone methides (o‐QMs) and aza‐analogs (aza‐o‐QMs), aza‐fulvene and triaza‐diene intermediates.

Coordination‐Driven Orthogonal Ligand Pairings through Dual Hydrogen‐Bonding/π‐π Interaction Complementarity

Chemistry – A European Journal, EarlyView.
A series of bidentate ligands for square‐planar Pd(II) complexes were developed, each with hydrogen‐bonding and π‐π‐stacking domains that are complementary to only one other ligand. The bis‐bidentate complexes form orthogonally to one another with high fidelity, but only when both interaction types are exploited in tandem.

Proton Conductivities of Stepwise Protonated Imidazole‐Fused Tetraphenylene Derivatives

Chemistry – A European Journal, EarlyView.
Proton conducting tetraphenylene molecules (ImTP) containing a imidazole group were controlled by the degree of protonation. By controlling the degree of protonation from neutral ImTP to H1ImTP⁺, H2ImTP2⁺, and H4ImTP⁴⁺, we demonstrated that the balance between intermolecular hydrogen bonding and electrostatic interactions affects structural stability ...
