ABSTRACT:
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.
