反応手順

A stirred solution of 158 g, (0.6 mole) of triphenylphosphine in 800 ml of xylene is treated with 97 g of 4-chlorobenzyl chloride. The resulting solution is heated (product begins to crystallize at this point) and refluxed for six hours. After standing overnight at room temperature, the solid is filtered, washed with xylene and then with ethyl acetate, and dried in a desiccator to yield 161 g of colorless solid [(4-chlorophenyl)methyl]triphenylphosphonium chloride; m.p. 283°-285°.
