Pd-catalyzed decarboxylative Heck vinylation of 2-nitrobenzoates in the presence of CuF₂.

ABSTRACT: A new protocol for the decarboxylative Heck vinylation of benzoic acids is disclosed. In the presence of a catalyst system generated in situ from Pd(OAc)₂ (2 mol %), CuF₂ (2 equiv), and benzoquinone (0.5 equiv) in NMP, a wide range of olefins were coupled with various 2-nitrobenzoates at 130 ° C with the release of carbon dioxide to afford the corresponding vinyl arenes in good yields.
