The reactivity of some Ni(II)-tertiary phosphine complexes, NiX2L2 (X=Cl, Br, I; L=tertiary alkylphosphine), towards the RONa (R=Me, Et, Ph, PhCH2) alkoxides under carbon monoxide, has been studied. Whereas their reactions with methoxide yield trans-NiXL2COOCH3 methoxo-carbonyl complexes, those with the other alkoxides lead to the formation of organic and inorganic products such as aldehydes, hydrocarbons
在一氧化碳下,某些Ni(II)-叔膦配合物NiX2L2(X = Cl,Br,I; L =叔烷基膦)对RONa(R = Me,Et,Ph,PhCH2)醇盐的反应活性为研究过。它们与甲醇的反应生成反式NiXL2COOCH3甲氧羰基配合物,而与其他醇盐的反应则导致有机和无机产物的形成,例如醛,烃,CO2或衍生物,Ni(II)和Ni(0)化合物。可以通过假设反应导致不稳定的NiXL2(OR)烷氧基配合物的形成来解释此行为,该配合物可以与CO反应生成烷氧基羰基NiXL2COOR,或者分解为Ni化合物和有机产物。烷氧基配合物尚未分离出来,但在某些情况下,已获得其形成的光谱证据。此外,
