実験手順
A solution of bromoarene 2 (1.544 g, 7.11 mmol) (or any haloarene of choice); tri-o-tolyl-phosphine (280 mg; 0.9 mmol) and trkdibenzylidene acetone)dipalladium(0) (280 mg; 0.3 mmol) in N,N-dimethylformamide (6 mL) and ethyl diisopropyl amine (3 mL) was treated with prop-2-en-1-ol (3 mL, 40 mmol) (or any alken-1-ol of choice, 6 eq.) and the solution was stirred at 120° C. for 3 h under nitrogen. The reaction mixture was concentrated under high vacuum and the residue was purified by flash chromatography (eluent 5% MeOH in dichloromethane) to afford the aldehyde 80 (253 mg, 18% yield).
