反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: In a similar manner, when p-methylsulfinylbenzyl chloride is used, the product is p-methylsulfinylbenzyltriphenylphosphonium chloride, melting point 258°-262°C with gasing.

实验步骤: NaH (55-65%; 0.1 g; about 2 mmol) was introduced into a solution of 24a (0.31 g; 1.0 mmol) in absolute THF (15 ml). The initial charge was stirred at room temperature for 5 min, and 4-methylsulfinylbenzyl chloride (3, 0.19 g; 1.0 mmol) was added. The reaction mixture was stirred at room temperature for 2 h. The yellow-brown solution was diluted with H2O and neutralized with 10% strength citric acid. The THF was removed and the aqueous solution was extracted with ethyl acetate (2×). The combined organic extract was washed with saturated NaCl solution (2×), dried over Na2SO4 and concentrated. The solids residue was purified by column chromatography (SiO2 60, CH2Cl2/EtOH 9.5+0.5). M.p. 179° C.
