71 4.2. Synthesis of (E)-2,3-diphenylacrylic acid 2a by using novel Fe(CO)5/t-BuOK/AcOH/CH2Cl2 reagent system %Spectr., General procedure: The Fe(CO)5 (1.0 mL, 7.5 mmol) was added dropwise to a solution of anhydrous t-BuOK (0.84 g, 7.5 mmol) 29 %Spectr. in THF (25 mL) at 25 °C under dry nitrogen. The contents were stirred for 45 min at 60 °C and brought slowly to 25 °C. Acetic acid (0.43 mL, 7.5 mmol) was added and the contents were stirred for 1 h at 25 °C. Dichloromethane (5 mL) was added and the contents were stirred for another 1 h. Then diphenylacetylene (0.22 g, 1.25 mmol) was added and further stirred for 10 h. The metal carbonyl complexes were oxidized using CuCl2*2H2O (2.55 g, 15 mmol) in acetone (10 mL). Saturated NaCl solutionwas added and the contents were extracted with ether (2 x 40 mL), dried over anhydrous Na2SO4 and concentrated under reduced pressure. The residuewas subjected to column chromatography (silica gel, hexaneeEtOAc). Ethyl acetate (10percent) in hexane eluted the (E)-2,3-diphenylacrylic acid 2a.
