Abstract Mechanical-force-induced redox catalysis has recently advanced rapidly, emerging as a green and innovative tool in synthetic chemistry. The foundation of this strategy lies the single electron transfer (SET) from polarized piezoelectric materials to substrates, which is initiated by potential generated through mechanical agitation. magnitude primarily influenced intrinsic properties material. In certain circumstances, however, may be insufficient trigger SET process, akin limitations visible-light excitation photocatalytic reactions. This challenge motivated us explore effective solutions. work, we establish catalytic system that utilizes consecutive mechanical-force-induced (ConMET) strategy. novel employs mechanochemical catalysts, with 9-phenyl-dihydroacridine (D1) serving sacrificial donors, facilitating produce significantly more powerful reductive species during grinding. Our approach effectively promotes reduction aryl iodides, bromides even electron-rich chlorides, possess potentials high − 2.8 V (vs. SCE), leading formation radicals. Ultimately, enables anti-Markovnikov hydroarylation alkenes dehalogenative deuteration aromatic halides (Cl, Br) under mild conditions.
