A POLYMERIC, PHOSPHORUS-CONTAINING COMPOSITION DERIVED FROM ARYL TO ARYL COUPLING OF A SUBSTITUTED 2,2'-DIHYDROXYL-1,1'-BINAPHTHALENE OR A SUBSTITUTED 2,2'-DIHYDROXYL-1,1'-BIPHENYLENE AND PHOSPHONYLATED AT THE DIOXYL OF SAID STRUCTURE WITH AT LEAST ONE DIARYLOXYPHOSPHITE [-P(-O-AR)²], DIARYLPHOSPHINE [-P(AR)²] AND/OR ARYL,ARYLOXYPHOSPHINITE [-P(AR)(-O-AR)], WHERE EACH AR IS INDIVIDUALLY PHENYL, SUBSTITUTED PHENYL, NAPHTHYL, AND SUBSTITUTED NAPHTHYL, PROVIDED THAT THE TWO AR GROUPS THAT ARE DIRECTLY OR INDIRECTLY BONDED TO THE SAME PHOSPHORUS ATOM MAY BE LINKED TO EACH OTHER BY A LINKING UNIT SELECTED FROM DIRECT BOND, ALKYLIDENE, SECONDARY OR TERTIARY AMINE, OXYGEN, SULFIDE,SULFONE AND SULFOXIDE. POLYMERIZATION BY ARYL TO ARYL COUPLING IS ACHIEVED BY DIRECT OXIDATIVE COUPLING OF THE BINAPHTHALENE OR BIPHENYLENE, COPOLYMERIZATION WITH AN AROMATIC COMONOMER, OR COPOLYMERIZATION WITH AN ALDEHYDE. THE PHOSPHONYLATION MAY BE PERFORMED PRIOR TO OR AFTER POLYMERIZATION. THE POLYMERIC, PHOSPHORUS-CONTAINING COMPOSITIONS IN COMBINATION WITH A GROUP VIII METAL AND, OPTIONALLY A LEWIS ACID, ARE PARTICULARLY USEFUL IN THE CATALYTIC HYDROCYANATION OF UNSATURATED ORGANIC COMPOUNDS, ISOMERIZATION OF UNSATURATED, BRANDED NITRILES TO UNSATURATED LINEAR NITRILES, AND HYDROFORMYLATION OF UNSATURATED ORGANIC COMPOUNDS.
