Mechanochemical Synthesis of Boroxine-linked Covalent Organic Frameworks

Author(s): Hamzehpoor E; Effaty F; Borchers TH; Stein RS; Wahrhaftig-Lewis A; Ottenwaelder X; Frišcic T; Perepichka DF; ...

We report a rapid, room-temperature mechanochemical synthesis of 2- and 3-dimensional boroxine covalent organic frameworks (COFs), enabled by using trimethylboroxine as a dehydrating additive to ov ...

Cooperative Sensitization Upconversion in Solution Dispersions of Co-Crystal Assemblies of Mononuclear Yb3+ and Eu3+ Complexes

Author(s): Sun G; Xie Y; Wang Y; Mandl GA; Maurizio SL; Zhang H; Ottenwaelder X; Capobianco JA; Sun L; ...

Lanthanide upconversion luminescence in nanoparticles has prompted continuous breakthroughs in information storage, temperature sensing, and biomedical applications, among others. Achieving upconve ...

Resonant acoustic mixing (RAM) for efficient mechanoredox catalysis without grinding or impact media

Author(s): Effaty F; Gonnet L; Koenig SG; Nagapudi K; Ottenwaelder X; Frišcic T;

Resonant acoustic mixing (RAM) enables mechanoredox catalysis with BaTiO3 as the piezoelectric catalyst on model diazonium coupling reactions. RAM proceeds without formal grinding or impact media, is faster than the analogous ball-milling strategy, and is r ...

Intramolecular H-bond stabilization of a primary hydroxylamine in salen-type metal complexes

Author(s): Singh H; MacKay A; Sheibany N; Chen F; Mosser M; Rouet PÉ; Rousseau F; Askari MS; Ottenwaelder X; ...

Primary hydroxylamines, RNHOH, decompose readily in the presence of transition metal ions. We show that this reactivity can be arrested by ligand design via an intramolecular hydrogen bond. Six met ...

Programmed Synthesis of Tetra-Aryl Thiophenes with Stepwise, Ester-Controlled Regioselectivity

Author(s): Messina C; Ottenwaelder X; Forgione P;

Herein, we report a modular synthetic route to access tetra-arylated thiophene compounds with four different substituents with programmed chemical control provided by an ester activating/directing group. This method enables the functionalization of individu ...

Five Nitrogen Oxidation States from Nitro to Amine: Stabilization and Reactivity of a Metastable Arylhydroxylamine Complex.

Author(s): Zsombor-Pindera J; Effaty F; Escomel L; Patrick B; Kennepohl P; Ottenwaelder X;

Redox noninnocent ligands enhance the reactivity of the metal they complex, a strategy used by metalloenzymes and in catalysis. Herein, we report a series of copper complexes with the same ligand framework, but with a pendant nitrogen group that spans five ...
