As an intermediate of the Saegusa oxidation of the silyl enol ether 1, the novel, structurally highly unusual d Pd-tetraolefin complex 2 was isolated; 2 is the first complex of this type whose solid-state geometry has been fully elucidated. Apparently, the enone formed in the course of the reaction is conformationally preorganized to act as a host for the palladium atom. TMS=trimethylsilyl.
作为甲硅烷基烯醇醚1的Saegusa氧化反应的中间体，分离得到了新型的、结构上极为不寻常的二钯 - 四烯烃配合物2；2是此类配合物中第一个其固态几何结构已被完全阐明的。显然，反应过程中形成的烯酮在构象上预先组织好以作为钯原子的主体。TMS = 三甲基硅基。
