    • 8 (50 mg, 0.370 mmol) were placed in a glass tube and degassed. Dry oxygen-free THF (2 ml) was introduced by vacuum transfer and the mixture was allowed to warm from -78°C to room temperature overnight with stirring. The solution turned an intense green color. The solvent was replaced by hexane, and then the resulting potassium salt and graphite were filtered off in a glove box (a box equipped with gloves in which air- and moisture-sensitive compounds can be handled). After evaporation of the solvent, pentane was added and the solution was cooled at -30°C to give emerald green crystals of 2 (53 mg, 73%).
