Reaction Conditions:

with C₃₅H₂₀F₃₄NO₃^(1-)*Pd⁽²⁺⁾*Cl^(1-);N-ethyl-N,N-diisopropylamine in neat (no solvent) at 130; for 0.333333 h;Microwave irradiation;

Steps:

8 Alkoxycarbonylation of aryl halide and alcohol: general procedure

General procedure: A mixture of the aryl halide (1.0 mmol), alcohol (5.0 equiv), Mo(CO)6 (0.5 equiv), DIPEA (1.5 equiv) and palladacycle 1 (1 mol % Pd) was heated in a pressure tube at 130 °C under microwave irradiation. The reaction was monitored by TLC. When the reaction has completed, the reaction mixture was cooled to room temperature and the alcohol was removed. The crude mixture was subjected to F-SPE to remove palladacycle 1 (see general procedure for the recycling of palladacycle 1) and the solution of crude product was concentrated, diluted with EtOAc (20 mL) and washed successively with 2 M HCl (210 mL) and water (10 mL). The organic layer was driedover anhydrous MgSO4, filtered and concentrated to give pure 6.
