Acetophenones, as a group of phenolic compounds, produced by many plants of various families for some reasons such as repelling insects [1]. The proven ability of acetophenone-rich plants to fend off pests and insects has shed light on the perspective of using acetophenone derivatives as pe...
Perfume and Fragrance Industry: Acetophenone is widely used in the perfume and fragrance industry due to its pleasant odor. It is used as a fragrance ingredient in perfumes, soaps, lotions, and other personal care products. The mechanism of action in this field is its ability to contribute to...
acid catalyst, then either chlorinating the acetylated product, adding a buffering base and further chlorinating to form the corresponding alpha , alpha , alpha -trichloroacetophenone or reacting the acetylated acetophenone with hypochlorite to form the corresponding benzoic acid and reacting the acid...
Acetophenone oxime reacts with ethylmagnesium bromide to give the dihydro-1,2-oxazine (118) and this with nitrous acid affords 3,5-diphenyl-6H-1,2-oxazine (119). The proposed mechanism en route to the initial product is complex, but there seems no reason why this synthesis could not be...
The U.S. EPA has classified acetophenone as a Category D, not classifiable as to human carcinogenicity. Environmental Fate It is unclear what mechanism is responsible for the central nervous system depression observed following high doses of acetophenone. In vitro evaluations have demonstrated ...
The major fragments in the spectra are due to α-fission to oxonium ions. A correlation between the intensities of the oxonium ions and Hammett substituent constants is noted. Rearrangements are examined by means of deuterium labelling and low electron voltage studies....

Full selectivity to target benzylideneacetophenone was achieved over ZnO, ZrO2 and MgO, while benzaldehyde disproportionation to benzyl alcohol and benzoic acid (Cannizzaro reaction) was promoted using SiO2 and CeO2. A direct correlation between activity and specific (per m) Lewis catalyst basicity ...
Kinetic studies indicate that the reaction is first-order with respect to ketone and butyric acid, except at very high acid concentrations, and independent of the manganese concentrations as long as these exceed 0.008 M . The results are most satisfactorily described by a mechanism involving eno...
