Participants

Conditions

Temperature: 25 °C

Procedure

Potassium diphenylmethanide (5.72 g, 27.8 mmols) in about 50 mL of THF was slowly added to 6,6-dimethylfulvene (2.94 g, 27.8 mmols) in about 100 mL of THF at about 25 C. The reaction mixture was stirred at about 25° C. for about 16 hours. The solvent was removed under reduced pressure to give the desired product as a sticky, oily solid.
