Poly(meta-phenylene oxides) for the design of a tunable, efficient, and reusable catalytic platform.

We present poly(meta-phenylene oxides) as versatile and tunable scaffolds for immobilized catalyst design. Their modular synthesis enables the rational incorporation of different side chain groups with positional control along the polymer backbone, providing an easy means to modulate polymer properties, and their corresponding catalytic activity. The coordinative convolution of these polymers with (NH4)2PdCl4 affords efficient, reusable catalysts for various organic transformations.
