Synthesis, structural elucidation and catalytic activity toward a model Mizoroki–Heck C–C coupling reaction of the pyrazolic Tröger’s base Pd4Cl8(PzTB)2 complex

The synthesis of a novel palladium (II) complex Pd4Cl8(PzTB)2, where PzTB is a pyrazole Tröger’s base analogue ligand is reported. A complete structure elucidation of the complex was achieved by spectroscopic and crystallographic data, exhibiting a metallomacrocycle supramolecular structure and a planar-square geometry on each palladium atom. This complex exhibited also a high activity and selectivity toward a model Mizoroki–Heck C–C coupling reaction of styrene with some iodobenzene derivatives.
