observed. Chloride abstraction from either 3–5 or 7, 8 using Ag[BF4] gave the cationic complexes [RuCl(η6-p-MeC6H4Pri)Ph2PCH2N(H)C5H3(Cl-5)N-P,N}][BF4] 9, [RhCl(η5-C5Me5)Ph2PCH2N(H)C5H3(Cl-5)N-P,N}][BF4] 10, [Pd(C12H12N)Ph2PCH2N(H)C5H3(Cl-5)N-P,N}][BF4] 11 and cis-[MPh2PCH2N(H)C5H3(Cl-5)N-P,N}2][BF4]2 (M = Pt 12 or Pd 13) in which 1 chelates through both P and Npyridyl donor atoms. All complexes were
由Ph 2 PCH 2 OH和2-H 2 NC 5 H 3(Cl-5)N合成了一种新的官能化吡啶基膦Ph 2 PCH 2 N(H)C 5 H 3(Cl-5)N 1。1与H 2 O 2水溶液反应,得到Ph 2 P(O)CH 2 N(H)C 5 H 3(Cl-5)N 2。在两种情况下,1和2的晶体结构均显示通过N–H···N吡啶基形成二聚体对 或N–H··OP分子间氢键。的任一氯桥裂解[的RuCl(μ-Cl)的(η 6 - p -MeC 6 ħ 4镨我)} 2 ],[的RhCl(μ-Cl)的(η 5 -C 5我5)} 2 ]或[的Pd(C 12 H ^ 12 N)(μ-Cl)的} 2 ]与两个当量1,得到单核配合将[RuCl 2(η 6 - p -MeC 6 ħ 4镨我)1 ] 3,[的RhCl2(η 5 -C 5我5) 1 ] 4或[的PdCl(C 12 H ^ 12 N) 1 ]
