Then, 4-iodotoluene (2.0 mmol, 0.26 mL) as well as 8 mL DMA (containing 0.5 M H2O) were transferred to the tube by syringe under N2. The mixturewas stirred at 70 C for 20 h. The solutionwas washed withH2O and ether. The organic layer was extracted twice with ether. It was then purified by Centrifugal Thin Layer Chromatography (CTLC)using CH2Cl2 as eluent. The solvent was removed under reduced pressure. The yield of 5a is 98% (0.0848 g, 0.0980 mmol). The residue was subjected to crystallization process by CH2Cl2 and hexanesand yellow crystals were resulted. Similar processes were taken forthe preparation of 5b except that dicyclopentadiene (2.0 mmol,0.264 g) was used. The yield of 5b is 98% (0.0922 g, 0.0980 mmol). Yellow crystals were resulted in crystallization process by CH2Cl2and heptane.
