Ortho effect in hydrolysis of phenyl esters was written by Nishioka, Takaaki;Fujita, Toshio;Kitamura, Koji;Nakajima, Minoru. And the article was included in Journal of Organic Chemistry in 1975.Recommanded Product: 35065-86-2 This article mentions the following:
The kinetics of the alk. hydrolysis of substituted phenyl esters of acetic acid, N,N-dimethylcarbamic acid, di-Et phosphate, and N-methylcarbamic acid were studied using uv spectroscopy. The logarithmic value of the second-order rate constant was correlated using log k = ρσo,m,p + δEs + fF + c, where Es and F are the Taft-Kutter-Hansch steric and the Swain-Lupton-Hansch field effect constants of ortho substituents, resp. By means of the resp. susceptibility constants, ρ δ, and f, the role of ortho substituents in the hydrolysis reaction course was analyzed quant. In the experiment, the researchers used many compounds, for example, 3-Bromophenyl acetate (cas: 35065-86-2Recommanded Product: 35065-86-2).
3-Bromophenyl acetate (cas: 35065-86-2) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Recommanded Product: 35065-86-2
