Supported bis(phosphorus) ligands are disclosed for use in a variety of catalytic processes, including the isomerization, hydrogenation, hydroformylation, and hydrocyanation of unsaturated organic compounds. Catalysts are formed when the ligands are combined with a catalytically active metal, such as nickel.

What is claimed is: 1. A polymer-supported diol of the formula: wherein Pol and Q are connected via a carbon-carbon bond; Q is an organic ring structure; and Pol is an insoluble polymer support; comprising a diol grafted onto a polymer selected from the group consisting of a benzyl halide-containing polymer or a olefin-containing polymer; wherein the benzyl halide-containing polymer is attached to an aromatic carbon of the diol through a benzylic carbon or the olefin-containing polymer is attached to an aromatic carbon of the diol through an olefinic carbon; wherein said diol is selected from the group consisting of (a) biphenol, C, wherein each R is independently selected from the group consisting of H, C1 to C20 branched or straight chain alkyl and benzyl, C1 to C20 cycloalkyl, C6 to C20 aryl, OR1, CO2R1, and cyclic ether; wherein neighboring R1 groups are optionally connected to form a ring structure; wherein each R1 is independently selected from the group consisting of C1 to C20 branched or straight chain alkyl, C1 to C20 cycloalkyl, and C6 to C20 aryl; and wherein x and y are each independently 0-3, and x and y are each independently 0-4 if at least one of Rx or Ry contains an aromatic ring; and (b) binaphthol, D, wherein each R is independently selected from the group consisting of H, C1 to C20 branched or straight chain alkyl and benzyl, C1 to C20 cycloalkyl, C6 to C20 aryl, OR1, CO2R1, and cyclic ether; wherein each R1 is independently selected from the group consisting of C1 to C20 branched or straight chain alkyl, C1 to C20 cycloalkyl, and C6 to C20 aryl; wherein x and y are each independently 0-5, and x and y are each independently 0-6 if at least one of Rx or Ry contains an aromatic ring, and combinations thereof. 2. A polymer-supported bis(phosphorous) ligand (2) having the formula, wherein Pol and Q are connected via a carbon-carbon bond; Q is an organic ring structure; Pol is an insoluble polymer support; and X is selected from the group of alkoxide, aryloxide, alkyl or aryl; comprising the reaction product of the polymer supported diol of claim 1 with a phosphorous halide of the formula PYnX3-n, wherein Y is a halide; X is selected from the group consisting of alkoxide, aryloxide, alkyl and aryl; and n=3, 2, or 1; and wherein, when X is an alkoxide, aryloxide, alkyl or aryl, X may contain from 1 to 50 carbon atoms, heteroatoms, or functional groups selected from the group consisting of ethers, alcohols, esters, and amides. 3. The polymer-supported diol of claim 1 wherein the benzyl halide-containing polymer is attached to an aromatic carbon of the diol through a benzylic carbon or the olefin-containing polymer is attached to an aromatic carbon of the dial through an olefinic carbon. 4. A polymer-supported bis(phosphorous) ligand (2) having the formula, wherein Pol and Q are connected via a carbon-carbon bond; Q is an organio ring structure; Pol is an insoluble polymer support; and X is selected from the group of alkoxide; aryloxide, alkyl or aryl; comprising the reaction product of the polymer supported dial of claim 3 with a phosphorous halide of the formula PYnX3-n, wherein Y is a halide; X is selected from the group consisting of alkoxide, aryloxide, alkyl and aryl; and n=3, 2, or 1; and wherein, when X is an alkoxide, aryloxide, alkyl or aryl, X may contain from 1 to 50 carbon atoms, heteroatoms, or functional groups selected from the group consisting of ethers, alcohols, esters, and amides.
