    摘要: Allylic esters of tetrabromophthalic acid are formed using allylic alcohol both as a reactant and a solvent. In the first step, the alcohol and a base are reacted with tetrabromophthalic anhydride to form the half-ester sodium salt. In the second step, the half-ester sodium salt is reacted with allylic halide to form the diester which crystallizes from solution. The excess solvent may be treated to recover the raw materials or recycled.
