Reaction Conditions:
tetrakis(triphenylphosphine) palladium(0) in ethanol;hexane;toluene;
Steps:
P.3.1 Preparation Example 3-1
Preparation Example 3-1 To a suspension of tetrakis(triphenylphosphine)palladium (213 mg) in toluene (7 ml) was added 2-chloro-4-iodotoluene (2.33 g) at room temperature. The mixture was stirred at room temperature for 30 min, and thereto were added a solution of phenylboronic acid (1.35 g) in EtOH (2 ml) and 2M aqueous sodium carbonate solution (9.25 ml), and the mixture was refluxed under heating. After 3 hr, the reaction mixture was cooled and the organic layer was separated. The aqueous layer was extracted with hexane (4 ml). The organic layers were combined, washed with saturated aqueous sodium hydrogencarbonate solution (4 ml) and saturated brine (4 ml), and dried over anhydrous magnesium sulfate. After filtration, the filtrate was concentrated, and hexane (10 ml) and silica gel (4 g) were added to the residue (2.11 g). The mixture was stirred at room temperature for 1 hr. Silica gel was filtered off and the filtrate was concentrated to give 2-chloro-4-phenyltoluene as a pale-brown oil (1.86 g, 99.4%). 1H-NMR(CDCl3): 2.40(3H, s), 7.23-7.60(8H, m).
