Scheme 4. The scope of various non-conjugated alkenes.^{a a}Reactions were carried out by using (–)-sparteinePdCl₂ (0.03 mmol, 10 mol%), (–)-sparteine (0.06 mmol, 20 mol%), Na₂CO₃ (0.3 mmol, 1.0 equiv.), 1 (0.3 mmol, 1.0 equiv.), phenylboronic acid 2a (0.6 mmol, 2 equiv.), and 4-methoxyphenyl iodide 3a (0.9 mmol, 3 equiv.) in the mixture of DCM/H₂O/CH₃CN (2 mL : 0.4 mL : 0.2 mL) for 24 h at 100 °C under a N₂ atmosphere. ^bThe reaction was conducted for 36 h and 4.0 equiv. of 3a were used. ^cAn alkene substrate (0.2 mmol) was used in the reaction.
