As an intermediate of the Saegusa oxidation of the silyl enol ether 1 , the novel, structurally highly unusual d 10 Pd 0 –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.
