摘要：

Reactions of CpRuCl(PPh3)(2) with bis(phosphino)amines, X2PN(R)PX2 (1 R = H, X = Ph; 2 R = X = Ph; 3 R = Ph, X-2 = O2C6H4) give neutral or cationic mononuclear complexes depending on the reaction conditions. Reaction of 1 with CpRuCl(PPh3)(2) gives one neutral complex, [CpRu(Cl)(eta(2)-Ph2PN(H)PPh2)] (4) and two cationic complexes, [CpRu(eta(2)-Ph2PN(H)PPh2)(eta(1)-Ph2PN(H)PPh2)]Cl (5) and [CpRu(PPh3)(eta(2)-Ph2PN(H)PPh2)]Cl (6), whereas the reaction of 2 with CpRuCl(PPh3)(2) leads only to the isolation of cationic complex, [CpRu(PPh3)(eta(2)-Ph2PN(Ph)PPh2)]Cl (7). The catechol derivative 3, in a similar reaction, affords an interesting mononuclear complex [CpRu(PPh3){eta(1)-(C4H4O2)PN(Ph)P(O2H4C6)}(2)]Cl (8) containing two monodentate bis(phosphino)amine ligands. The structural elucidation of the complexes was carried out by elemental analyses, IR and NMR spectroscopic data. (C) 1998 Elsevier Science S.A. All rights reserved.
