실험 절차

First, 20 ml of tetrahydrofuran was added dropwise slowly to the mixture of 0.50 g of dihydro tetrakis(triphenylphosphine)ruthenium and 3.00 g of (4-(trifluoromethyl)benzyl)malononitrile under an atmosphere of nitrogen , followed by stirring for 15 minutes. Then, 0.82 g of acrolein was added dropwise slowly, followed by stirring for 1 hour at room temperature and then the solvent was distilled away. The residue was subjected to silica gel column chromatography to give 1.58 g of 2-(2-formylethyl)-2-(4-(trifluoromethyl)benzyl)malononitrile (the intermediate (19)).
