  New palladium complexes with phosphino- and phosphinitopyridine ligands

  摘要：

  Three new palladium complexes containing a difunctional P, N-chelate, namely tris(chloro{[1-methyl-1-(6-methyl-2-pyridyl) ethoxy] diphenylphospine-kappa(2) N, P} methylpalladium( II) chloroform solvate, 3[Pd(CH3) Cl(C21H22NOP)] center dot CHCl3, (III), dichloro[2-(2,6-dimethylphenyl)-6-(diphenylphosphinomethyl) pyridine-kappa(2) N, P] palladium(II), [PdCl2(C26H24NP)], (IV), and chloro[2-(2,6-dimethylphenyl)-6-(diphenylphosphinomethyl) pyridine- kappa(2) N, P] methylpalladium(II), [Pd(CH3) Cl( C26H24NP)], ( V), are reported. Geometric data and the conformations of the ligands around the metal centers, as well as slight distortions of the Pd coordination environments from idealized square-planar geometry, are discussed and compared with the situations in related compounds. Non-conventional hydrogen-bond interactions (C - H center dot center dot center dot Cl) have been found in all three complexes. Compound ( III) is the first six-membered chloro - methyl - phosphinite P, N-type Pd-II complex to be structurally characterized.

  [NiCl2(P,N)] complexes 9−12. These Ni(II) complexes are paramagnetic in solution, as determined by the Evans method. Whereas they were inactive for the oligomerization of ethylene in the presence of methylalumoxane (MAO), they provided activities up to 61 000 mol of C2H4/((mol of Ni) h) (11) in the presence of only 6 equiv of AlEtCl2. The selectivities for C4 olefins were as high as 92% (12 with 2
