I. General Information Unless otherwise noted, all commercially available compounds were used as provided without further purification. Solvents for chromatography were technical grade and freshly distilled prior to use. Diisopropyl ether used in reactions was analytical grade and distilled from benzophenone/na. Analytical thin-layer chromatography (TLC) was performed on Merck silica gel aluminium plates with F-254 indicator, visualised by irradiation with UV light. Column chromatography was performed using silica gel (Macherey Nagel, particle size 0.040-0.063 mm). Solvent mixtures are understood as volume/volume. 1 H-NMR and 13 C-NMR were recorded on a Varian AV300, AV400 or AV600 spectrometer in CDCl 3 and are reported relative to the solvents residual 1 H-signal (CHCl 3, δ(h) 7.26). Data are reported in the following order: chemical shift (δ) in ppm; multiplicities are indicated s (singlet), bs (broad singlet), d (doublet), t (triplet), m (multiplet); coupling constants (J) are in Hertz (Hz). Melting points were measured using open glass capillaries in a Buchi SMP-20 apparatus. IR spectra were recorded on a Perkin Elmer-100 spectrometer and are reported in terms of frequency of absorption (cm -1 ). Mass spectra (EI-MS, 70 ev) were conducted on a Finnigan SSQ 7000 spectrometer. HRMS were recorded on a Thermo Scientific LTQ Orbitrap XL spectrometer. S2

IV. Preparation of B-Alkyl-9-BBNs The B-alkyl-9-BBN could be generated in situ from the corresponding alkenes with 9-BBN dimer. As mentioned in Fu s paper, 9 in a nitrogen-filled glovebox the corresponding olefin (0.32 mmol) was added to 9-BBN dimer (39.0 mg, 0.16 mmol) in a 10-mL vial equipped with a stirring bar. Diisopropyl ether (1.0 ml) was added and then the vial was capped and removed from the glovebox. The reaction mixture was stirred at 60 C for 1.5 h, and allowed to cool to room temperature. The vial was then taken back into the glovebox and could be directly used in the catalytic reactions. V. Typical Procedure for the Catalytic Reactions In a nitrogen-filled glovebox, an oven-dried sealed tube containing a stirring bar was charged with aryl pivalate substrate (0.20 mmol), yellow Ni(COD) 2 (4.4 mg, 8 mol%), IPr. HCl ligand (13.6 mg, 16 mol%), cesium carbonate (97.7 mg, 0.30 mmol) and freshly distilled diisopropyl ether (1.0 ml). Subsequently, the B-alkyl-9-BBN solution was added via syringe, and the reaction mixture was stirred at 110 C for 12 h. Upon purification via column chromatography the pure product was obtained after solvent removal. S12

VI. Gram Scale Experiment In a nitrogen-filled glovebox, 1-allyl-4-methoxybenzene (1.08 ml, 7.01 mmol) was added to 9-BBN dimer (854.1 mg, 3.50 mmol) in a 100-mL sealed tube equipped with a stirring bar. Distilled diisopropyl ether (21.9 ml) was added and then the tube was capped and removed from the glovebox. The reaction mixture was stirred at 60 C for 1.5 h, allowed to cool to room temperature, and then taken back into the glovebox. Another 100-mL oven-dried sealed tube containing a stirring bar was charged with naphthalen-2-yl pivalate (1a, 1.00 g, 4.38 mmol), yellow Ni(COD) 2 (24.0 mg, 2 mol%), IPr. HCl ligand (74.4 mg, 4 mol%), cesium carbonate (2.14 g, 6.57 mmol) in the glovebox. Subsequently, the prepared B-alkyl-9-BBN solution was added via syringe, and the reaction mixture was stirred at 110 C for 68 h. After it was cooled down to room temperature, the reaction mixture was extracted three times with ethyl acetate. The combined organic layer was washed with brine, dried over Na 2 SO 4, and then filtrated. The filtrate was concentrated in vacuo and the residue was purified by flash column chromatography (eluent: pure hexane to 50:1 hexane:etoac) to afford the corresponding product 3a as a white solid in 46% yield.
