摘要：

(Chemical Equation Presented) Ménage à quatre: The Pd 4 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. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
