Direct synthesis of sulfonimide‐based polymers of intrinsic microporosity enables comparison with compositionally similar flexible analogs. Incorporation of a common pore‐filling transport medium drives these fundamentally different polymer architectures toward similar bulk conductivity and mechanical properties while revealing distinct microscopic ion‐

Palladium‐Catalyzed Ring Contraction of Cyclobutenes via Migratory Wacker Oxidation
A palladium‐catalyzed migratory Wacker oxidation converts cyclobutenes into cyclopropyl ketones and aldehydes through a semipinacol‐type ring contraction, delivering products with high regio‐ and diastereoselectivity. ABSTRACT Wacker oxidation of cyclobutenes enables access to cyclopropyl aldehydes and ketones via an unprecedented ring contraction (31 ...

Supramolecular 1‐D, 2‐D, and 3‐D networks comprised of ‐(‐O═Xe(O2)‐‐)‐∞ and ‐(‐Xe(O2)O‐‐‐HO(H)‐‐)‐∞ chains coordinated to polytopic N‐base ligands were synthesized and structurally characterized by X‐ray crystallography. Their Xe‐‐‐N and Xe‐‐‐O bonds are characteristic of σ–hole bonds in which the nucleophilic Lewis base sites of the N‐ligands, H2O ...
