โฆ Synopsis
Dedicated to Professor K . Freudenberg on his 80th birthduy
The photolysis of cyclopentadiene at ca. -1OOC in the presence of ketonic sensitizers is reported [21 to afford the products (I)-(3) in equal proportions. We found that photolysis at -78OC with either acetone or benzophenone as sensitizer [31 yields in addition to (1)-( 3), the compounds (4) and (6), and various polymers of cyclopentadiene.

A 9 mol% Y 2 O 3 -stabilized ZrO 2 specimen was annealed in boiling water for 1200 h, and the phase structure was examined by XRD and the chemical states of zirconium, yttrium and oxygen were examined by XPS. After annealing, the phase of the specimen remains entirely cubic, and the chemical states
