A Unique Pd₄ Platform with CH₃ and μ‐CH₂ Groups and Its CC Coupling Reaction with Simple Olefins

Abstract

Ménage à quatre: The Pd4 complex 1 features both terminal CH3 and bridging CH2 groups, and it reacts with ethylene at room temperature to give mainly propene. NMR spectroscopic studies reveal several intermediates in the formation of 1 from Pd2 building blocks.
