In the autoxidation of 3, 3 '-methylenebis(guaiazulene) CAD at 100°C in HMPA (or DMF), eight products including two known compounds MO and CE) were separated. All the new compounds (CA8), CA4), CB), CC), [Di), and [DO) were derivatives of 8-(3-guaiazulenyl)-3, 7-dimethylbenzofulvene whose structures were established on the basis of spectroscopic (UV, MS, IR, and NMR) data. Possible reaction pathways through radical reaction schemes are discussed for the formation of these eight products.
