Reaction mixtures and methods using catalysts and reaction conditions to produce significantly improved yields (and thereby higher purity) of olefin metathesis products, with greatly reduced amounts of impurities. These techniques include in one instance reduction in temperature of reaction, and in another, the use of chemical compounds that act as reaction inhibitors of unwanted reactions to minimize or prevent formation of unwanted impurities.
                            反应混合物和方法使用催化剂和反应条件,以产生显著提高烯烃交换产物的收率(从而提高纯度),并大大减少杂质的量。这些技术包括在一种情况下降低反应温度,在另一种情况下使用
化学化合物作为不需要反应的反应
抑制剂,以最小化或防止不需要的杂质的形成。
