(6)), and with Tlacac (1:2 molar ratio) with formation of the acetylacetonate [Pd(acac)[C(H)PPh(3)](2)CO}](ClO(4)), 7. On the other hand, complex 3 reacts with the ylide Ph(3)P=C(H)CN (1:2 molar ratio) giving [Pd[C(H)PPh(3)](2)CO}[NC-C(H)=PPh(3)](2)](ClO(4))(2), 8, which contains two N-coordinated ylides, and with NBu(4)OH (1:1) to give [Pd(&mgr;-OH)[C(H)PPh(3)](2)CO}](2)(ClO(4))(2), 9. The reaction
Pd(OAc)(2)与双(phosph)盐[Ph(3)PCH(2)COCH(2)PPh(3)] Cl(2)(1:1摩尔比)的反应导致形成-二氯双(内酯)衍生物Cl(2)Pd [C(H)PPh(3)](2)CO},1的合成,其中双(内酯)配体[C(H)PPh(3) ](2)CO通过两个内酰胺碳原子充当螯合基团。配合物1与TlClO(4)(1:1摩尔比)反应,得到[Pd(&mgr; -Cl)[C(H)PPh(3)](2)CO}](2)(ClO(4) )(2),2与NCMe中的另外两个等价的TlClO(4)反应,得到[Pd [C(H)PPh(3)](2)CO}(NCMe)(2)](ClO( 4))(2)3.已探究2和3的反应性。化合物2与吡啶,3,5-二甲基吡啶或Ph(3)P = C(H)CN(1:2摩尔比)反应,导致氯桥联系统破裂并形成[PdCl [C( H)PPh(3)](2)CO}(L)](ClO(4))(L
