The activation of the inert C-O bonds in mesylates through the use of a new class of imidazolyl phosphines allows the decarboxylative coupling of aryl mesylates as well as polysubstituted alkenyl mesylates. Variation of the ligands leads to two complementary methods providing the corresponding biaryls and polysubstituted olefins in good yields. Copyright

Chemical Equation Presented At 50°C lower than the best known copper catalysts, a catalytic silver(I)/ palladium(II) system allows the decarboxylative cross-coupling of arenecarboxylates with aryl triflates at temper-atures as low as 120°C. Remarkably, polychlorinated and many heterocyclic arenecarboxylates are converted for the first time in high yields. FG = functional group.
Pd-catalyzed decarboxylative Heck vinylation of 2-nitrobenzoates in the presence of CuF2

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.
