General Description

Cyclopropanone is a highly reactive and unstable organic compound with the chemical formula C3H4O. It is a cyclic ketone with a three-membered ring structure, and its molecule is characterized by a significant amount of ring strain, which makes it highly reactive. Cyclopropanone is used in organic synthesis and as a building block in the production of pharmaceuticals and agrochemicals. Due to its instability, it is typically used in situ and its commercial availability is limited. Its reactivity and unique structure make it an interesting target for synthetic chemists and researchers seeking to develop new methods for the construction of cyclic molecules.

PHOTOLYSIS OF ALLENE-OZONE MIXTURES AT 647 nm IN CRYOGENIC MATRICES. Part 1. Formation of allene oxide

Matrix studies of the photolytic reaction at 647 nm between allene and ozone were carried out at 12 K.Primary photoproducts include carbon monoxide, acrolein (cis and trans), cyclopropanone, ketene, ethylene, allene oxide, and formaldehyde.In Ar and Kr matrices both acrolein and cyclopropanone are produced in high yields, whereas in Xe matrices cyclopropanone is the major product.Infrared spectra for cyclopropanone and ith oxygen-18 and deuterium substitutes are reported.The carbonyl stretch for cyclopropanone is observed at 1815 cm-1 in an Ar matrix.Also reported is the first synthesis of allene oxide.The carbon-carbon double bond stretch is observed at 1823.4 cm-1 and it exhibits a small oxygen-18 shift.The change in product distribution is discussed in terms of heavy atom spin-orbit enhancement of singlet-triplet excitation, so that in xenon reaction takes place on a triplet surface, whereas in argon it occurs on a singlet surface.
