A simple and mild acylation of alcohols, phenols, amines, and thiols with a reusable heteropoly acid catalyst (H6P2W18O62閻?4 H2O) was written by Romanelli, Gustavo P.;Bennardi, Daniel O.;Autino, Juan C.;Baronetti, Graciela T.;Thomas, Horacio J.. And the article was included in E-Journal of Chemistry in 2008.Application In Synthesis of 3-Bromophenyl acetate This article mentions the following:
The acylation of alcs., phenols, thiols, and amines with varied substitution using acid anhydrides is efficiently catalyzed by Wells-Dawson heteropoly acid (H6P2W18O62閻?4 H2O). Reactions proceed with very good to excellent yield in air at room temperature, using toluene as solvent (40 examples). The bulk catalyst was easily reused without appreciable loss of its activity. In the experiment, the researchers used many compounds, for example, 3-Bromophenyl acetate (cas: 35065-86-2Application In Synthesis of 3-Bromophenyl acetate).
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.Application In Synthesis of 3-Bromophenyl acetate
