The initial attack of ozone occurs in both stressed and unstressed rubber to give a molozonide, which is unstable and dissociates to give a Zwitterion (1) and a carbonyl compound (2).
A number of [alpha], [beta]-unsaturated carbonyl compounds were prepared by condensing of 2-formylfuran, 2-formylpyridine and 2-formylthiophene with acetone, acetophenone, 3-methyl-acetophenone, [alpha]-chloroacetophenone and ethyl methyl ketone in ethanolic NaOH solutions.
Researchers have found that the gas phase of mosquito coil smoke contains some carbonyl compounds with properties that can produce strong irritating effects on the upper respiratory tract--for example, formaldehyde and acetaldehyde (Chang and Lin 1998).
21-23), (51) Furthermore, for carbonyl compounds with an [alpha]-proton, a tautomeric equilibrium can exist between the imine and the enamine, but in which the imine form predominates.
Gold, moreover, is less reactive than copper and does not appear to form significant amounts of a carbonyl compound under the conditions found in pottery kilns, so it remains in the glaze, where any particles that form are presumably either too small or too large to exhibit significant colour unless the glaze has a suitable composition.
In most cases these precursors have been prepared from carbonyl compounds via reductive alkylation of protected hydrazines [3-5] (Scheme 1, A).

The third essay, titled 1,2-cycloaddition reaction of carbonyl compounds and pentaatomic heterocyclic compounds, by three chemists at the university of the Basilica in Potenza, Italy, concerns the Paterno-Buchi reaction on Furan derivatives and on pentaatomic heterocycles differing from Furan.
Studies on polyatomic molecules are concerned principally with inductive and mesomeric effects in the (pi(*),pi) electronically excited states of substituted benzenes and the effects of conjugation on the energies, geometries and stabilities of singlet and triplet (pi(*)n) excited states of organic carbonyl compounds.
