Swinging palladaporphyrin: A palladacyclopentadiene has been incorporated into the porphyrinoid frame. A transformation of 21,23-ditelluraporphyrin triggered by coordination of palladium(II) resulted in the replacement of a tellurium atom by a palladium atom to form aromatic 21-pallada-23-telluraporphyrin. The nonplanar molecule is in equilibrium between two asymmetric forms.
