Electronic interactions in phenyl acetates and acetanilides was written by Freedman, H. H.. And the article was included in Journal of the American Chemical Society in 1960.Related Products of 35065-86-2 This article mentions the following:
The infrared stretching frequency of CO increases in amides and esters of unsaturated alcs; this has been given 2 different interpretations, (a) inductive effect, by analogy with α-halo ketones, and (b) inhibition of contributing CO resonance forms. Evidence is presented for (a) being dominant in PhOAc (I), and (b) in PhNHAc (II). Uniplanar structures were found sterically hindered (Stuart Briegleb mol. models); the smallest admissible average angle between the acetyl and phenyl planes of I (II) is 60° (37.5°), and, therefore, the resonance energy retained from uniplanar contributions is only 25% (65%). Carbonyl absorption peaks are compared of I, II, and PhAc (III) with a m- or p-NO2, CN, Br, Cl, Ac, CHO, OAc, NHAc, Ph, OMe, OH, NH2, or Me substituents. Whereas the associated frequency shifts (Δν) for II and III are linear with Hammett’s 6 constants, this is not observed for I; also, Δν for electron-attracting substituents in p is twice as large in II as in I; all of which supports the proposed theory. In the experiment, the researchers used many compounds, for example, 3-Bromophenyl acetate (cas: 35065-86-2Related Products of 35065-86-2).
3-Bromophenyl acetate (cas: 35065-86-2) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Related Products of 35065-86-2
