Patent ID: 8618319

Claim:
A metal complex represented by formula (D): wherein: M represents Ni or Pd; R 3 represents hydrogen or a hydrocarbon group having 1 to 20 carbon atoms and optionally containing a heteroatom; L 1 represents a ligand coordinated to M; R 3 and L 1 optionally bind each other to form a ring; X 1 represents oxygen or sulfur; E 1 represents phosphorus, arsenic or antimony; R 4 each independently represents hydrogen or a hydrocarbon group having 1 to 20 carbon atoms and optionally containing a heteroatom, wherein at least one of R 4 is a hydrocarbon group having two or more heteroatom-containing groups; R 10 , R 11 , and R 12 each independently represent hydrogen, a halogen, a hydrocarbon group having 1 to 30 carbon atoms and optionally containing a heteroatom, OR 2 , CO 2 R 2 , CO 2 Mâ€², C(O)N(R 1 ) 2 , C(O)R 2 , SR 2 , SO 2 R 2 , SOR 2 , OSO 2 R 2 , P(O)(OR 2 ) 2-y (R 1 ) y , CN, NHR 2 , N(R 2 ) 2 , Si(OR 1 ) 3-x (R 1 ) x , OSi(OR 1 ) 3-x (R 1 ) x , NO 2 , SO 3 Mâ€², PO 3 Mâ€² 2 , P(O)(OR 2 ) 2 Mâ€² or an epoxy containing group; R 13 represents a hydrocarbon group having 1 to 30 carbon atoms and optionally containing a heteroatom; R 1 represents hydrogen or a hydrocarbon group having 1 to 20 carbon atoms; R 2 represents a hydrocarbon group having 1 to 20 carbon atoms; Mâ€² represents an alkali metal, an alkaline earth metal, ammonium, quaternary ammonium or phosphonium; x represents an integer of 0 to 3; and y represents an integer of 0 to 2, such that a plurality of groups selected from the group consisting of R 4 , R 10 , R 11 , and R 12 optionally bind each other to form an aliphatic ring, an aromatic ring, or a hetero ring containing a heteroatom selected from the group consisting of oxygen, nitrogen and sulfur, said rings being an optionally-substituted 5 to 8 membered ring.
