摘要:
The allyl complex di-mu-chloro-bis[(1,2,3-eta)-1-carboxy-3-(1-hydroxyethyl)allyl]dipalladium (which is a hydroxyl-containing palladium 11 Sally] complex based on sorbic acid) has been synthesized from trans,trans-2,4-hexadienic (sorbic) acid and Na2PdCl4 in an aqueous solution. The complex has been isolated from the reaction solution and has been characterized by IR, H-1 NMR, and C-13 NMR spectroscopy. Its composition has been determined by elemental analysis. The protodemetalation kinetics of the complex in aqueous solutions has been studied. The rate of this reaction obeys a second-order equation, first-order with respect to each reactant. A reaction mechanism has been derived from protodemetalation kinetics and data characterizing the state of the reactants.
