  Switchable Decarboxylative Heck-Type Reaction and Oxo-alkylation of Styrenes with N-Hydroxyphthalimide Esters under Photocatalysis

  摘要：

  The switchable visible-light-mediated decarboxylative Heck-type reaction and oxo-alkylation reaction of N-hydroxyphthalimide esters under photocatalysis were developed. Disubstituted or trisubstituted alkenes were obtained in good yield with high E-selectivity in the presence of Bronsted acid as the additive, while ketones resulted in the absence of the acidic additive.

  The first photoinduced copper-catalyzed dual decarboxylative cross-coupling of α,β-unsaturated carboxylic acids and redox-active esters has been developed. This reaction enabled C(sp2)–C(sp3) bond formation, which afforded a variety of synthetically valuable alkene derivatives. Many α,β-unsaturated carboxylic acids and redox-active ester derivatives were tolerant to this reaction. The reaction also
