Procedure: To a solution of 1-bromo-2-cyclohexyl-benzene (5 mmol) in dioxane (20 mL) was added solid Pd(OAc)2 (0.1 g) and solid CsCO3 (10 mmol). tert-Butyl carbamate (7 mmol) was added to the reaction mixture, and the contents were heated at 80° C. for 2 h. The reaction mixture was cooled to room temperature and filtered through Celite. The solvent was removed in vacuo and the residue obtained was purified by flash column chromatography using DCM as eluant to yield (2-cyclohexylphenyl)-carbamic acid tert-butyl ester. The reaction mixture was cooled to room temperature filtered through Celite The solvent was removed in vacuo the residue obtained was purified by flash column chromatography

Procedure: A Schlenk tube was charged with CuI (9.6 mg, 0.050 mmol, 5.0 mol %), NaI (300 mg, 2.00 mmol), evacuated and backfilled with argon. Racemic trans-N,N′-dimethyl-1,2-cyclohexanediamine (16 μL, 0.10 mmol, 10 mol %), l-bromo-2-cyclohexylbenzene (97% pure; Lancaster; 186 μL, 1.00 mmol), n-pentanol (1 mL) were added under argon. The Schlenk tube was sealed with a Teflon valve and the reaction mixture was stirred at 130° C. for 40 h. The resulting suspension was allowed to reach room temperature and filtered through silica gel (1×0.5 cm) eluting with hexane (50 mL). The filtrate was concentrated, and the residue was purified by flash chromatography on silica gel (hexane) to provide the known 1-iodo-2-cyclohexylbenzene (283 mg, 99% yield; ca. 97% pure) as a colorless liquid.
