Cage Effect on Oxidation of Dimethyl Sulfoxide via Pd2L4 Prolate Spheroids

摘要

Self-assembly of PdX2 (X~- = NO3~-, BF4~-, and CF3SO3~-) with 2,6-bis(4'-nicotinamidephenoxy)naphtha-lene (L) forms a series of [Pd2L4]X4 prolate spheroids. The O donors of two Me2SO molecules within the prolate spheroid cage are oriented toward the Pd(II) metal centers. In the presence of H2O2, the nestled Me2SO within the cage is efficiently oxidized to Me2SO2 at room temperature.
