8. An ether solution of methyllithium (0.357 mmol) was added to a stirred solution of 2 (167 mg, 0.17 mmol) in 5 mL of THF under an atmosphere of dinitrogen. The green-brown solution turned dark purple immediately and then faded to orange-brown over a period of 1 h. The solvent was evaporated in vacuo, and the oily orange residue was dissolved in a minimum amount of methylene chloride. The extract was filtered, pentane was added, and the mixture was cooled to -40°C to yield orange cubes; yield 104 mg (0.12 mmol, 72%).
9. A THF solution of 2 (10 mL of THF per 100 mg) and MeLi (in 10 mL of ether per 2.1 equiv) were separately degassed three times by freeze-pump-thaw cycles. The reaction vessel was then filled with the desired gas, and the solutions were combined. The rapidly formed dark purple color that was generated in the case of 5 and 6 faded over a period between 1 h and 3 days. The product was isolated in a manner analogous to the isolation of 3.
