  Synthesis and characterization of PdII complexes containing cyclic bis-ylides

  摘要：

  The reaction of Ph2PCH2PPh2 (dppm) with ClCH2C(O)CH2Cl (1:1 molar ratio) in refluxing CHCl3 gives the new ylide-phosphonium salt 1, through quaternization of the two P atoms of the dppm and spontaneous loss of HCl. Compound 1 reacts with NEt3 in CHCl3 or CH2Cl2 solution (1:1 molar ratio) giving a mixture of the bis-ylide compound 2a and the ylide-methanide 2b (molar ratio 2a:2b = 1:2). This mixture (prepared in situ) reacts with PdCl2(NCMe)(2) to give the corresponding dichloride(bis-ylide) complex 3a (coordination through the two ylidic carbons) and the dichloride(ylide-methanide) complex 3b (coordination through the ylide carbon and the methanide carbon). in a molar ratio 3a:3b = 1:2. The reaction of the mixture 3a:3b with AgClO4 (1:2 molar ratio, NCMe or Me,CO) in the presence of neutral ligands L gives the corresponding mixtures of the dicationic complexes [Pd(L)(2)(C,C-bis-ylide)](ClO4)(2) (4a. L = NCMe: 5a. L = pyridine) and [Pd(L)(2)(C,C-ylide-methanide)](ClO4)(2) (4b, L = NCMe; 5b, L = pyridine) (molar ratio 4a:4b = 1:2; molar ratio 5a:5b = 3:1). On the other hand the reaction of Ph2PCH2PPh2 (dppm) with ClCH2C(=CH2)CH(2)Ct (1:1 molar ratio) in refluxing ClCH2CH2Cl gives the bis-phosphonium salt 6. This salt reacts with (LiBu)-Bu-t and PdCl2(NCMe)(2) (1:2.2:1 molar ratio) in THF affording the ylide-methanide complex 7. The crystal structures of complexes 3b(.)3dmso and 7(.)CHCl(3) have been determined by X-ray diffraction. (C) 2002 Elsevier Science B.V. All rights reserved.
