Photolysis of allene-ozone mixtures at 647 nm in cryogenic matrices: Part 1. Formation of allene oxide

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