Mechanochemical Synthesis of Aryl Fluorides by Using Ball Milling and a Piezoelectric Material as the Redox Catalyst

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(39)

Published: July 31, 2023

Abstract Aryl fluorides are important structural motifs in many pharmaceuticals. Although the Balz–Schiemann reaction provides an entry to aryl from aryldiazonium tetrafluoroborates, it suffers drawbacks such as long time, high temperature, toxic solvent, gas release, and low functional group tolerance. Here, we describe a general method for synthesis of tetrafluoroborates using piezoelectric material redox catalyst under ball milling conditions presence Selectfluor. This approach effectively addresses aforementioned limitations. Furthermore, can be recycled multiple times. Mechanistic investigations indicate that this fluorination may proceed via radical pathway, Selectfluor plays dual role both source fluorine terminal reductant.

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

Chemical Communications, Journal Year: 2022, Volume and Issue: 59(8), P. 1010 - 1013

Published: Dec. 12, 2022

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 analogous ball-milling strategy, and readily scalable. X-ray diffraction spectroscopy indicate that reusability of a under might be limited by boration.

Ferroelectrics as emerging and attractive catalysts have shown tremendous potential for applications including wastewater treatment, hydrogen production, nitrogen fixation, organic synthesis, etc. In this study, we demonstrate that molecular ferroelectric crystal TMCM-CdCl3 (TMCM = trimethylchloromethylammonium) with multiaxial ferroelectricity superior piezoelectricity has an effective catalytic activity on the direct construction of pharmacologically important substituted quinoline derivatives via one-pot [3 + 2 1] annulation anilines terminal alkynes by using N,N-dimethylformamide (DMF) carbon source. The recrystallized crystals from DMF remain well piezoelectricity. Upon ultrasonic condition, periodic changes in polarization contribute to release free charges surface domains nano size, which then quickly interacts substrates solution trigger pivotal redox process. Our work advances a route not only providing valuable direction ferroelectrics but also further enriching executable range catalysis. Molecular possess switchable spontaneous polarization.

Organic Reactions Enabled by Mechanical Force‐Induced Single Electron Transfer

Chemistry - A European Journal, Journal Year: 2024, Volume and Issue: 30(47)

Published: June 18, 2024

Mechanochemical reactions, achieved through milling, grinding, or other mechanical actions, have emerged as a solvent-free alternative to traditional solution-based chemistry. Mechanochemistry not only provides the opportunity eliminate bulk solvent use, reducing waste generation, but also unveils new reaction strategy which enables realization of reactions previously inaccessible in solution. While majority organic facilitated by force traditionally follow two-electron transfer pathways similar their counterparts, field mechanochemically induced single-electron (SET) has witnessed rapid development. This review outlines examples mechanochemical SET process, focusing on reagents that initiate SET, thereby positioning mechanochemistry burgeoning within realm
