A Remarkably Active Iron Catecholate Catalyst Immobilized in a Porous Organic Polymer

A single-site, Iron catecholate-containing porous organic polymer was prepared and utilized as a stable and remarkably active catalyst for the hydrosilylation of ketones and aldehydes. In some instances, catalyst loadings of 0.043-2.1 mol % [Fe] Were sufficient for complete hydrosilylation of aldehydes and ketones within IS mm at room temperature. The catalyst can be recycled at least three times without a drop in,catalytic activity. This system is an example of an immobilized homogeneous catalyst with no hemogeneous. analogue.
