Selective dimerization of a trinuclear mixed-metal sandwich complex: construction of an axially chiral metal skeleton

Certain metal sandwich complexes undergo dimerization through metal-metal bond formation. Here, we found that a reductive dimerization of mixed-metal Pd 2 Pt or PdPt 2 sandwich complexes proceeds through selective Pt-Pt bond formation. A restricted rotation at the Pt-Pt bond of the PdPt 2 dimer gave...

Description
Summary:Certain metal sandwich complexes undergo dimerization through metal-metal bond formation. Here, we found that a reductive dimerization of mixed-metal Pd 2 Pt or PdPt 2 sandwich complexes proceeds through selective Pt-Pt bond formation. A restricted rotation at the Pt-Pt bond of the PdPt 2 dimer gave a unique axially chiral structure derived from a heterometal arrangement in a mixed-metal cluster. We report reductive dimerization of mixed metal Pd 2 Pt or PdPt 2 sandwich complexes. The dimerization occurs through selective Pt-Pt bond formation, and the PdPt 2 dimer has a unique axially chiral structure derived from the heterometal arrangement.
