product showed that the yield of allylsulfone compound vii was 78 9 mg of palladium chloride 0 05 mmol and 254 mg 1 mmol of sodium p toluenesulfinate tetrahydrate were suspended in methanol 1 ml a solution of 52 0 2 mmol mg of triphenylphosphine 211 mg 0 5 mmol purity 98 3 of sulfone compound iii and 60 mg 1 mmol of acetic acid in toluene 3 ml was added thereto and stirred for 3 hours at 60 u00b0 c for 3 hours after the reaction water and an aqueous saturated sodium chloride solution were poured into the reaction mixture and extracted with ethyl acetate the obtained organic layer was washed with an aqueous saturated ammonium chloride solution and an aqueous saturated sodium chloride solution in this order and dried over anhydrous magnesium sulfate and filtered the filtrate was evaporated to give a crude product hplc analysis of the product showed that the yield of allylsulfone compound vii was 76 9 2 6 mg of palladium chloride 0 015 mmol 156 mg 0 6 mmol of triphenylphosphine and 452 mg 1 8 mmol of sodium p toluenesulfinate tetrahydrate were suspended in methanol 1 ml and 46 mg 0 45 mmol of triethylamine and toluene 3 ml were added thereto and stirred at 60 u00b0 c at 10 hours after the reaction water was poured into the reaction mixture and extracted with ethyl acetate the obtained organic layer was washed with an aqueous saturated ammonium chloride solution.
