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
Acetophenone 1 (0.5 g, 1.68 mmol) was dissolved in dry methanol (20 mL) until a clear solution.

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.
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%).
