Aminophosphine류가 배위된 전이금속(Pd, Ni) 착물의 촉매반응; I. 탄소-탄소 짝지움 반응

다국어 초록 (Multilingual Abstract)

Several transition metal complexes, [M(L)X₂](M=Pd(Ⅱ), Ni(Ⅱ); X=CI, Br) are prepared with aminophosphine ligands such as 1,2-bis{(diphenylphosphino)amino}ethane{Ph₂PNHCH₂CH₂NHPPh₂}(L₁), 1,2-bis{(diphenylphosphino)amino}propane{Ph₂PNHCH(CH₃)CH₂NHPPh₂}(L₂), trans-1,2-bis{(diphenylphosphino)amino}cyclohexane{Ph₂PNHC?H?NHPPh₂}(L₃) and 1,2-bis{(diphenylphosphino)amino}benzene{Ph₂PNHC?H₄NHPPh₂}(L₄). The properties of these complexes are characterized by optical spectroscopic methods including UV/vis spectroscopy, CD, IR, ¹H- and ?P-NMR together with conductometer and elemental analysis. All complexes are stable under atmospheric environment. Catalytic reactivity for C-C coupling between [M(L)X₂] and Grignard reagents(RMgX; R=phenyl, propyl, buthyl) by thermolysis were investigated utilizing GC/mass, ¹H- and ?C-NMR. When mol scale is 1:20 at [Pd(L)Cl₂] and Grignard reagents, the high catalytic activity for C-C coupling is apparent. The [M(L)X₂](X=Cl, Br) complexes which have strong bond at M-P exhibit high yields for C-C coupling reactions. When the central metal ion is Pd(Ⅱ), the high catalytic activity for C-C coupling is apparent. The complex coordinated with Br shows higher catalytic activity for C-C coupling reactions compared to Cl.
