【摘要】 本文从分子轨道对称守恒原理出发，讨论了一些对称禁阻有机协同反应在金属催化剂的作用下，由于反应物的分子轨道与金属催化剂表面原子的轨道发生相互作用，由原来的对称禁阻变成了对称允许的催化活化机理．更多还原

【Abstract】 in this paper, with the point of view of molecular symmetry conservationprinciple, it was discussed that some symmetry-forbidden reactions become symmetry-allowedones because of the interaction between molecular orbitals of reactants and atomic orbitals ofmetal catalyst surface.更多还原
