Pentachloropentadienic acid was isolated, apart from the expected 5,5-dimetoxytetrachlorocyclopentadiene, in the reaction of hexachlorocyclopentadiene with potassium hydroxide in methanol. The structure of this minor product was established by X-ray crystallography. The plausible mechanism of its formation is discussed.
在六氯环戊二烯与氢氧化钾在甲醇中的反应中,除了预期的 5,5-二甲氧基四氯环戊二烯外,还分离出五氯戊二烯酸。这种次要产物的结构是通过 X 射线晶体学确定的。讨论了其形成的合理机制。
