実験手順

A mixture of 0.71 g (4.0 mmole) of palladium chloride, 2.1 g (8.0 mmole) of triphenylphosphine, 0.80 g (4.2 mmole) of cuprous iodide, 68.8 g (0.20 mole) of 5-chloro-2-iodobenzophenone, 200 ml of diethylamine, and 400 ml of methylene chloride was stirred at room temperature under argon until complete solution was obtained. In one portion, 40.0 g (0.22 mole) of N-propargylphthalimide was added to the solution and the resulting mixture stirred for 20 hr. The volatiles were removed at reduced pressure and the residue was triturated with 200 ml of iospropanol. The resulting precipitate was collected by filtration to give crude end product. Recrystallization from acetone gave cream colored prisms, mp 148°-150° C.
