Phosphorus-containing compositions and their use in hydrocyanation, isomerization and hydroformylation reactions

A phosphorus-containing, bidentate ligand monomer compound of the Formula I or of the Formula II,

• wherein:
• x=0 to 4;
• y=0 to 2;
• a and b are individually either 0, 1, or 2, provided a+b=2;
• each Ar is individually selected from the group consisting of phenyl, substituted phenyl, naphthyl, and substituted naphthyl, provided that the two Ar groups that are directly or indirectly bonded to the same phosphorus atom optionally are linked to each other by a linking unit selected from the group consisting of direct bond, alkylidene, —N(H)—, oxygen, —S—, —S(O)2—, and —S(O)—;
• each Ar optionally is further substituted with C1 to C20 branched or straight chain alkyl, C1 to C20 cycloalkyl, C6 to C20 aryl, alkoxy, cycloalkoxy, aryloxy, formyl, ester radical, fluorine, chlorine, bromine, perhaloalkyl, hydrocarbylsulfinyl, hydrocarbylsulfonyl, or hydrocarbylcarbonyl
• each R is individually selected from the group consisting of hydrogen, acryloyl, methacryloyl and an organic radical with a terminal acryloyl, or methacryloyl group;
• each R″ is individually selected from the group consisting of hydrogen, linear or branched alkyl, cycloalkyl, aryl, alkoxy, cycloalkoxy, aryloxy, formyl, ester radical, fluorine, chlorine, bromine, perhaloalkyl, hydrocarbylsulfinyl, hydrocarbylsulfonyl, or hydrocarbylcarbonyl;
• provided at least one R represents acryloyl, methacryloyl or the organic radical with a terminal acryloyl, or methacryloyl group.
