Abstract

Translocation of a lead cation from the N-core of a porphyrin to a hanging carboxylate group (I) is coupled to a transmetalation process with a 2nd lead cation, leading to a dinuclear species (II). A novel hanging-atop coordination mode is responsible for the dynamic and stereo-controlled binding of lead to the porphyrin core. [on SciFinder(R)]
