- Abstract
Herein, we present the divergent syntheses of α‐arylacylamides and oxindoles via mechanoredox chemistry by using easily accessible α‐bromo N‐sulfonyl amides as starting materials. Our system consists of a catalytic amount of CuII precatalyst and piezoelectric materials. The highly polarized BaTiO3 or PbTiO3 under mechanical agitation can act as an electron donor to realize the recycling of CuII and CuI. Control experiments and density functional theory calculations have been performed to support the proposed mechanistic rationale for the cascade reactions.
