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

Alcohol (20mmol), TEMPO-MNPs powder (200 mg), Mn[(N[O.sub.3]).sub.2](120 mg, 50% aqueous solution), Co[(N[O.sub.3]).sub.2] (120 mg, 50% aqueous solution), and 208.3 mg internal standard (acetophenone) in 15 mL of C[H.sub.3]COOH were stirred in a two-necked flask at 40[degrees]C.
Acetophenone: For the highest orbitals, B/eV = 9.37, 9.55, 9.77, and 11.91 [35] replaced the CCSD(T) value of 9.38 and the P3 values of 9.59, 9.55, and 12.21, respectively.

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 [118].
It has been displayed in animal models regarding fears of certain odors [36]; 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].
