Syntheses, X‐ray Crystal Structures, and Raman Spectra of Self‐Assembled XeO3 Chain and Network Complexes of Polytopic sp2‐ and sp3‐Nitrogen Bases

open access: yesAngewandte Chemie, EarlyView.
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 ...

Flavin Catalysts in Organic Synthesis

open access: yesAngewandte Chemie, EarlyView.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Reactions of Terminal Olefins With Iron Carbenes

open access: yesAngewandte Chemie, EarlyView.
Iron carbenes react with terminal olefins and show productive metathesis or metathesis‐divergent pathways depending on the nature of the olefin. Reactions proceed through 2π + 2π cycloadditions to generate transient metallacyclobutane intermediates that undergo cycloreversion to generate the metathesis product or the metathesis‐divergent β‐hydride ...
