    • This specification discloses a method for carrying out catalytic polystep organic reactions at low temperature. The method is applicable to reactions wherein an initial reactant forms at least one intermediate product in one step of the reaction and an intermediate product forms a desired product in another step of the reaction. One of these steps is catalyzed by an acid group or a basic group and another step is catalyzed by a metal group or a metal compound group. The reaction is carried out by contacting the initial reactant with an ion exchange resin containing chemically bonded thereto as catalytic sites an acid group or a basic group and containing finely dispersed therein as catalytic sites at a distance from the other catalytic sites of the order of molecular dimensions a metal group or a metal compound group.
    • 本说明书公开了一种在低温下进行催化多步态有机反应的方法。 该方法适用于其中初始反应物在该反应的一个步骤中形成至少一种中间产物并且中间产物在该反应的另一步骤中形成所需产物的反应。 这些步骤之一由酸基团或碱性基团催化,另一步骤由金属基团或金属化合物基团催化。 该反应通过使初始反应物与含有化学键合的离子交换树脂接触,作为酸性基团或碱性基团的催化位点,并将其细分散在其中作为催化位点,距离分子的其它催化位置一定距离 尺寸为金属组或金属化合物组。
