2 1. General Information Anhydrous solvents were prepared according to standard methods. Commercially available chemicals were used as received without further purification. NMR spectra were recorded on 300 MHz, 400 MHz and 600 MHz spectrometers. Chemical shifts are quoted in ppm relative to CDCl 3. High-resolution mass spectra (HRMS) were obtained with a Q-TOF (ESI). 2. Experimental Section 2.1 Preparation and characterization of substrates Procedure for the preparation of template (T 3 ) 1 Toa 100 ml round bottom flask was added 2-fluorobenzonitrile (20 mmol, 1.0 equiv), 2-fluoroaniline (20 mmol, 1.0 equiv) and t BuOK (42 mmol, 2.1 equiv). Next, 60 ml dry DMSO was added and the reaction wasstirred overnight at room temperature.the reaction was poured into ice waterand the resulting precipitate was filtered and washed with water to provide a crude solid. The crude productwaspurified either by column chromatography (EtOAc/hexanes = 1:4) or recrystallization from methanol.

Next, the acid chloride (1.0 mmol, 1.0 equiv.), prepared from the corresponding carboxylic acid and oxalyl chloride, was added dropwise to the reaction mixture at 0 o C. The reaction was stirred overnight, then quenched with water, and extracted with DCM three times.the combined organic extractsweredried over MgSO 4 and concentrated in vacuo. The crude product was purified by column chromatography (EtOAc/hexanes = 3:1) to yield the pure product in moderate yield.

The tube was evacuated then back-filled with O 2 (3 times, balloon), capped, and heated to 100 C for 48 hours. After cooling to room temperature, the reaction mixture was filtered through a pad of silica gel. The silica gel was washed with an additional 10 ml of DCM. The filtrate was concentrated in vacuo to afford crude products, which was purified by flash column chromatography on silica gel using hexanes/etoac (3/1) as the eluent to give the pure product. S20

To a 25 ml Schlenk-type sealed tube equipped with a magnetic stirring bar was added the substrate (0.1 mmol), [RhCp*Cl 2 ] 2 (3.1 mg, mmol), S40
41 Yield (%) Cu(CO 2 CF 3 ) 2 xh 2 O (28.9 mg, 0.1 mmol), CF 3 CO 2 H (0.1 mmol), olefin (0.5 mmol) and DCE (2.0 ml). The tube was evacuated then back-filled with O 2 (3 times, balloon), capped, and immersed into a pre-heated oil bath at 100 C. After the indicated time, the Schlenk-type tube was cooled by ice water. The reaction mixture was filtered through Celite and eluted with DCM (4 4 ml). The filtrate was concentrated in vacuo to afford crude products. The yield was determined by 1H NMR analysis of the crude product using CH 2 Br 2 as an internal standard. Each time point was repeated three times and the equations for the lines were determined by linear regression. The ratio of the slopes for these lines corresponds to the KIE Eq. 1 Eq Time (h) S41

43 2.7 The procedure for the 10 mmol reaction in Toluene To a 250 ml round-bottom flask was added a magnetic stir bar, substrate 1a (10 mmol), [RhCp*Cl 2 ] 2 (0.31 g, 0.5 mmol), Cu (CO 2 CF 3 ) 2 xh 2 O (2.89 g, 10 mmol), CF 3 CO 2 H (1.14 g, 10 mmol), dry toluene (150 ml) and Ethyl acrylate (5.00 g, 50 mmol). The system was equipped with a reflux condenser and was evacuated and then back-filled with O 2 (balloon, 3 times). Next, the reaction was refluxed for 48 hours. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate and water and the phases were separated. The aqueous layer was extracted with ethyl acetate three times. The combined organic extracts were dried over MgSO 4, filtered and concentrated in vacuo to afford crude products, which were purified by flash column chromatography on silica gel using hexanes/etoac (3/1) as the eluent to give the pure products in 75% combined yield (mono 55%, di 20% isolated).
