PPh2(C6H4COOH) (2a,b,c), PPh2(C6H4COONa) (2d), PPh(C6H4COOH)2 (4b,c) and P(C6H4COOH)3 (6b,c) with formation of the corresponding complexes [Pt(L)2Cl2] (3a,b,c,d, 5b,c, 7b,c). Halide abstraction from 3a by Ag+ promotes coordination of the ortho-carboxylate function to platinum, yielding [PtPPh2(C6H4COO-2)}PPh2(C6H4COOH-2)}Cl] (bd8) and [ovbar|PPh2(C6H4COO-2)}2] (bd9). Reaction of 1 with CO and 2a or
[Pt(COD)Cl2](1)与PPh2(C6H4COOH)(2a,b,c),PPh2(C6H4COONa)(2d),PPh(C6H4COOH)2(4b,c)和P(C6H4COOH)3(6b)反应,c)形成相应的配合物[Pt(L)2 Cl 2](3a,b,c,d,5b,c,7b,c)。Ag +从3a提取卤化物可促进原羧酸盐官能团与铂的配位,产生[Pt PPh2(C6H4COO-2)} PPh2(C6H4COOH-2)} Cl](bd8)和[ovbar | PPh2(C6H4COO- 2)} 2](bd9)。1与CO和2a或2b反应生成[Pt(CO)(L)Cl2](10a,b),其中1和2,3-双(二苯基膦基)马来酸酐收率[PtPh2PC = C(PPh2)COOOCO} Cl2 ](bd12)和[Pt Ph2PC(COOH)= C(COOMe)-PPh2} Cl2](13)。报告并讨论了1H,13C和31P
