    Abstract: Allylic esters of tetrachlorophthalic 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 tetrachlorophthalic anhydride to form the half-ester sodium salt. In the second step, the 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.
