[(η5-Cp*)Rh(L)Cl][PF6], 7/8 (L = L1/L2 ≡ (N, E) ligand), was formed. Complexes 1–8 were authenticated with 1H, 13C1H}, and 77Se1H} NMR spectroscopy, high-resolution mass spectrometry, elemental analyses, and single-crystal X-ray diffraction. The moisture- and air-insensitive complexes of Pd(II) (1, 2), Ru(II) (3, 4) and Rh(III) (5–8) were thermally stable. Palladium and rhodium (under base-free condition) species
2-(苯基硫基)乙胺,并用蒽-9-甲醛2-(苯硒基)乙胺的缩合导致Schiff碱[PHS(CH 2)2 C = N-9-C 14 H ^ 9 ](L1)和[PHSE (CH 2)2 C = N-9-C 14 H 9 ](L2)。Na 2 [PdCl 4 ]在室温下在丙酮-水混合物中处理L1 / L2 3小时,得到palladacycle [PdCl(C –,N,S / Se)](1/2 ; L1 / L2 –H =(C –,N,S)/(C –,N,Se))。的反应[(η 6 -C 6 H ^ 6)的RuCl(μ-Cl)的] 2与L1 / L2在甲醇中在室温下(随后加入NH的8小时4 PF 6),得到半夹心络合物[( η 6 -C 6 H ^ 6)的Ru(大号)CL] [PF 6 ],3/4:(大号= L1 / L2 ≡(N,E)配体)。的反应[(η 5 -Cp *)的RhCl(μ-Cl)的]
