Anthranilic acid has been anchored to polystyrene, and rhodium, palladium, platinum and ruthenium complexes of this modified polystyrene have been prepared. These catalysts will reduce a variety of olefinic and aromatic hydrocarbons, and also nitrile, nitro and carbonyl functional groups, said carbonyl groups being present in either ketones or aldehydes.

Heterogeneous catalytic hydrogenation

A process for the preparation of cyclic ethers which comprises reacting an alkanediol in which the hydroxyl groups are separated by a chain of at least four carbon atoms in the liquid phase of a catalyst comprising a palladium salt and a copper salt, and recovering the cyclic ether thus formed by a separation step such as distillation. The reaction is carried out in a molecular oxygen gaseous atmosphere. A preferred catalyst is palladium chloride in combination with a copper salt such as cupric chloride or cupric nitrate.

Production of cyclic ethers

A process for the preparation of hydroxy ethers which comprises reacting an epoxide compound with an organic hydroxy compound in the presence of a PdCl.sub.2 /CuCl.sub.2 /O.sub.2 catalyst system, and recovering the hydroxy ether thus formed from the reaction mixture by a separation step such as distillation. An alternative catalyst system is K.sub.2 PdCl.sub.6 /CuCl.sub.2 /O.sub.2.
