Reaction Conditions:
Stage #1:methyl-triphenylphosphonium iodide with n-butyllithium in tetrahydrofuran at -78; for 0.5 h;Inert atmosphere;
Stage #2:p-(iodophenyl)carboxaldehyde in tetrahydrofuran at 20 - 55; for 5.5 h;Inert atmosphere;
Steps:
1
Under N2, 16 g (40 mmol) of methyltriphenylphosphine iodide was added to 200 mL of THF and stirred.Cool to -78 ° C, add 20 mL (48 mmol) of t-butyl lithium, react for 30 min,Continue to add 9.3g (40mmol) of p-iodobenzaldehyde, stir for 30min, and then naturally warm to room temperature.After heating to 55 ° C, the reaction was carried out for 5 h, 20 mL of a saturated ammonium chloride solution was added, and THF was distilled off.Extracted with ethyl acetate, dried, filtered, concentrated and purified by column chromatographyObtained iodine styrene, yield 77%
