General method and Screening reaction conditions Chemicals and solvents were either purchased (puriss p.a.) from commercial supplier or purified by standard techniques. All reactions, if not stated otherwise, were performed in oven-dried glassware under a nitrogen atmosphere containing a teflon-coated stirrer bar and dry septum. Reaction media were saturated with Argon to exclude atmospheric oxygen. All reactions were monitored by GC using tetradecane as an internal standard. Response factors of the products with regard to tetradecane were obtained experimentally by analyzing known quantities of the substances. GC analyses were carried out using an HP- capillary column (Phenyl methyl siloxane, 0 m x 0 x 0., 00/.-0-00/, min at 0 C, heating rate 0 C/min, or 0 min at 00 C). Column chromatography was performed using a Combi lash Companion-Chromatography-System (Isco-Systems) and RediSep packed columns ( g). NMR spectra were recorded at ambient temperature using CDCl as solvent, with proton, carbon at 00/00, 00/0 MHz, respectively. Mass spectral data were acquired on a Varian GC-MS Saturn 00 T. The ionization was achieved by EI AGC. High resolution mass spectra were acquired on a Waters GCT Premium. Infrared spectra were recorded on Perkin Elmer Spectrum 00 T-IR Spectrometer with Universal ATR Sampling Accessory. The alkenyl bromides/chlorides a, b, c, e, f, g, h, i, j, a, c, j were prepared according to the literature procedures and identified by comparison of their spectra with those of authentic samples. d was purchased from Aldrich and used as received. The aromatic carboxylates were prepared from the corresponding aromatic carboxylic acids following the procedures below and were directly used. S

General procedure for the synthesis of potassium carboxylate salts A 0 ml, two-necked, round-bottomed flask was charged with the carboxylic acid (0.0 mmol) and ethanol (0.0 ml). To this, a solution of potassium t-butoxide (. g, 0.0 mmol) in ethanol (0.0 ml) was added dropwise over h. After complete addition, the reaction mixture was stirred for another h at room temperature. A gradual formation of a white precipitate was observed. The resulting solid was collected by filtration washed sequentially with ethanol ( 0.0 ml) and cold (0 C) diethyl ether (0.0 ml), and dried in vacuum to provide the corresponding potassium salts of the carboxylic acids. General procedure for the decarboxylative coupling An oven-dried, nitrogen-flushed 0 ml crimp cap vessel was charged with the potassium carboxylate (0. mmol,. equiv.), Pd( -acac) (. mg, 0.00 mmol, mol %), tri--naphthylphosphine (. mg, 0.0 mmol,.0 mol %), copper(i) chloride (. mg, 0.0 mmol, 0 mol %),, 0-Phenanthroline (. mg, 0.0 mmol, 0 mol %) and alkenyl bromide (0. mmol). A degassed mixture of NMP ( ml) and mesitylene ( ml) was added via syringe. The resulting solution was then stirred at 0 ºC for h. After the reaction was complete, the mixture was cooled to room temperature, diluted with sat. NaHC and extracted with ethyl acetate ( 0 ml). The combined organic layers were washed with water and brine, dried over MgS, filtered, and concentrated in vacuo. The residue was purified by column chromatography (Si, ethyl acetate/hexane gradient) yielding the corresponding product. S
