Remarkably High Reactivity of Pd(OAc)2/Pyridine Catalysts: Nondirected C-H Oxygenation of Arenes was written by Emmert, Marion H.;Cook, Amanda K.;Xie, Yushu J.;Sanford, Melanie S.. And the article was included in Angewandte Chemie, International Edition in 2011.Name: 3-Bromophenyl acetate This article mentions the following:
The rational optimization and general applicability of the catalytic system Pd(OAc)2/pyridine is described (see scheme). The catalyst shows excellent reactivity in the C-H oxygenation of simple aromatic substrates. The Pd/pyridine ratio is critical as the use of one equivalent of pyridine per Pd center leads to dramatic enhancements in both reactivity and site selectivity in comparison to Pd(OAc)2 alone. In the experiment, the researchers used many compounds, for example, 3-Bromophenyl acetate (cas: 35065-86-2Name: 3-Bromophenyl acetate).
3-Bromophenyl acetate (cas: 35065-86-2) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon鑱砨romine bond is electrophilic in nature. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.Name: 3-Bromophenyl acetate
