Hence, at high temperature, the benzaldehyde selectivity decreases in competition with the formation of acetophenone
and other products.
In order to device a facile, industrially applicable and economical strategy for selective bromination, the acetophenone
, used as model substrate, was subjected to [alpha]-bromination by using different reagentswhich rendered bromoproducts with different selectivities
1 (0.5 g, 1.68 mmol) was dissolved in dry methanol (20 mL) until a clear solution.

Studies performed by Shi and colleagues characterized two acetophenone
derivatives, 2-hydroxy-4,6-dimethoxyacetophenone and 2,4-dihydroxy-5-methylacetophenon, as plant antifungal agents .
It has been displayed in animal models regarding fears of certain odors ; in the cited study, aversive conditioning to acetophenone
was induced in F0 mice.
Some of the major compounds include monoterpene hydrocarbons (p-cymene, limonene, [alpha]-pinene, and [alpha]-terpinene), oxygenated monoterpenes (camphor, carvacrol, eugenol, and thymol), diterpenes (cembrene C, kaurene, and camphorene), sesquiterpene hydrocarbons ([beta]-caryophyllene, germacrene D, and humulene), oxygenated sesquiterpenes (spathulenol, caryophyllene oxide), monoterpene alcohols (geraniol, linalool, and nerol), sesquiterpene alcohol (patchoulol), aldehydes (citral, cuminal), acids (geranic acid, benzoic acid), ketones (acetophenone
, benzophenone), lactones (bergapten), phenols (eugenol, thymol, carvacrol, and catechol), esters (bornyl acetate, ethyl acetate), and coumarins (fumarin, benzofuran) [1, 4, 8, 13, 104, 105].
The host compounds were ethyl-1-hexanol (>99%), heptacosane (>95%), (+)-3-carene (>90%), hentriacontane (>95%), cis-3-hexenyl acetate (>97%), acetophenone
(>98.5%), tridecanone (>95%), and 1-octen-3-ol (>98%).
Other metabolites detected in the aerobic degradation of BTEX were acetic acid, benzyl alcohol, acetophenone
and propanol (32).
