摘要
Ozonolyses of nine acyclic (1a-i) and of two cyclic (14, 29) alpha-oxo-alkenes on polyethylene or in pentane afforded in eight cases (1d-i, 14, 29) isolable alpha-oxo-ozonides. alpha-Diozonides (9) are obtained from five of the acyclic alpha-oxo-alkenes (1 a, b, d, g, h). All isolated ozonides are labile; the 2,4-dinitrophenylhydrazones of the alpha-oxo-ozonides, however, are very stable. Decomposition of the alpha-oxo-ozonides affords not only the hitherto known fragments, but non-peroxidic isomers (8) of the ozonides, too.
