Triphenylphosphine-2,4,4,6-tetrabromo-2,5-cyclohexadienone complex was successfully used as a new reagent for the synthesis of carboxylic acid bromides which were isolated as individual substances or were identified by conversion into the corresponding anilides. The reaction is chemoselective, and it can be applied to polyfunctional compounds, e.g., hydroxy acids.
成功使用了三苯基膦-2,4,4,6-四溴-2,5-环己二烯酮配合物作为合成羧酸溴化物的新试剂,这些化合物作为单个物质被分离出来或通过转化为相应的酰苯胺来鉴定。该反应具有化学选择性,并且可以应用于多官能团化合物,例如羟基酸。
