The photo-isomerization of cyclopentadienone O-oxide isolated in low temperature matrices
Abstract
Discrepancies in recent reports from different laboratories on the i.r. spectrum of matrix-isolated cyclopentadienone O-oxide have now been reconciled by showing that two distinct isomers may be formed from cyclopentadienylidene and O2, and that one, a carbonyl oxide, may be converted photolytically into the other, a dioxirane.
