Synthesis and catalytic activity of allyl, methallyl and methyl complexes of nickel(II) and palladium(II) with biphosphine monoxide ligands: Oligomerization of ethylene and copolymerization of ethylene and carbon monoxide

The syntheses of new cationic nickel complexes {[η3- methallyl]Ni[κ2P,O-Ph2P(X)P(O)Ph2]}SbF6, (1)-(2) [X = (oC6H4) (1), (NH), (2)] have been accomplished. The complexes oligomerize ethylene to linear α-olefins with selectivities as high as 89%. A dependence of oligomerization grade and activity on backbone geometry was shown. New cationic allyl and methyl complexes of palladium(II) [(CH3CN)(Me)Pd(κ2P,O- Ar2P(CH2)(n)P(O)Ar2)]X [n = 1-3, X = BF4, Ar=C6H5 (18-20)] [n = 1, X = SbF6, Ar =p-tolyl (23); n = 1 or 2, X = SbF6, Ar = C6H5 (21) or (22)]; [(ε3,C3H5)Pd(κ2P, O-Ph2P(CH2)(n)P(O)Ph2)]X, [n=2, X =triflate (10), tosylate (13); n=3, X =triflate (11), tosylate (14)], [(ε3- C3H5)]Pd(κ2P,O-Ar2P(CH2)(n)P(O)Ar2)]X, [n = 1, X = SbF6, Ar =p-tolyl (17); n = 2, X = SbF6 Ar = C6H5(16)] have been synthesized in good yields. These complexes have been used in the catalytic oligomerization of ethylene, and in the catalytic alternating copolymerization of ethylene and carbon monoxide, to yield polyketones.
