Studies on vic-Polycarbonyl Compounds. IV. Reaction of 1, 1-Diphenylcyclopentan-tetrone

In dehydration of 1, 1-diphenylcyclopentane-tetrone dihydrate (1) and in dehydrogenation of 1, 2-dihydroxy-4, 4-diphenylcyclopentene-3, 5-dione (4), the formation of 1, 1-diphenylcyclopentane-tetrone (3) was detected. The compound 3 reacted with stilbene at its two adjacent carbonyl groups to give t...

Description
Summary:In dehydration of 1, 1-diphenylcyclopentane-tetrone dihydrate (1) and in dehydrogenation of 1, 2-dihydroxy-4, 4-diphenylcyclopentene-3, 5-dione (4), the formation of 1, 1-diphenylcyclopentane-tetrone (3) was detected. The compound 3 reacted with stilbene at its two adjacent carbonyl groups to give the 1, 4-cycloaddition products, 5 and 6. Dehydrating ability of 3 towards acenaphthene is comparable to that of ο-chloranil, and its redoxpotential was assumed to be 0.7-0.87 V.
