Abstract
The existence of the alleged isobindone has been disproved. The compound, mp 330 °C, formed as a byproduct in the aldol–retroaldol condensation reaction of 1,3-indandione is not isobindone but 1-(1,3-indandionyl-2)-3-(1,3-indandionyliden-2)indene. The compound, mp 337 °C, formed from bindone in pyridine solution has the composition C36H18O5.Keywords
