Pd(OAc)2 (3 mol %, 11 mg), PMe2Ph (5 mol %, 11 mg), 1-chloronaphthalen-2-yl trifluoromethanesulfonate (500 mg, 1.61 mmol), acrylonitrile (103 mg, 1.93 mmoli), triethylamine (242 mg, 2.4 mmol) and 15 mL of acetonitrile were added to a microvawe vial and the mixture was irradiated by MW at 120° C. for 1 h. At the conclusion of the reaction, the solvent was evaporated under reduced pressure and the residue was treated with dichloromethane and washed with water; the organic layer was filtered through a pad of silica gel with copious washings, concentrated, and purified by flash chromatography on silica gel eluted with petroleum ether/ethyl acetate (93:7) to give (2E)-3-(1-chloronaphthalen-2-yl)prop-2-enenitrile as colourless oil (120 mg, 35% yield).
