Preparation Of 3-chloro-2-Imino-1H-indole Derivatives, Their Late Transition Metal Complexes And Catalytic Behaviors

My research work was mainly composed of three parts:In the first part, a series of 2-imino-indole derivatives and their neutral nickel complexes have been synthesized and characterized. A single-crystal X-ray analysis of [Ni(C10H7)(C18H16ClN2)(PPh3)] showed the nickel center adopted a square-planar coordination geometry. These complexes act solely as effective catalysts for ethylene oligomerization with the activity up to 2.05 ?104 g ethylene mol-1 h-1, without using cocatalysts. The oligomers were olefins from C4 to C6.The steric effect, electronic effect and polymerization parameters have been systematically investigation.In the second part, these 2-imino-indole derivatives were treated with NaH and then react with CuCl2. The single crystal X-ray analysis confirmed that the structures of these bis-2-imino-indoleCu (II) complexes were distorted tetrahedral coordination sphere.In the third part, 2-formyl-3-chloro-indole (o-methoxylanil) was treated with NaH and then react with C1H7NiCl(PPh3)2. The single crystal X-ray analysis confirmed that the structure of bis-2-formyl-3-chloro-indole(o-methoxylanil)nickel(II) complexes possesses an octahedron configuration.
