    • Experimental Procedure In a typical experiment, a THF (0.5 mL) solution of Rh(acac)(coe)2 (8 mg, 0.019 mmol) was added to a THF (2 mL) slurry of Si-DPP (60 mg, 0.056 mmol, and the mixture was stirred for 5 h. To this mixture was added a THF (0.5 mL) solution of 2-vinylnaphthalene (135 mg, 0.87 mmol) followed by a THF (0.5 mL) solution of HBcat (126 mg, 1.05 mmol, The reaction was allowed to proceed for 18 h at which point the mixture was filtered through a small plug of Celite before solvent was removed under vacuum. The residual oil was dissolved in C6D6 (1 mL) and analyzed by multinuclear NMR spectroscopy.5a,10 Confirmation of product formation was carried out using GC-MS on products derived from a basic, oxidative workup.
