4-dihydroxyphenyl)-ethen-2-yl}-2,2′-bipyridine] which contains a 2,2′-bipyridyl binding site linked to a catechol binding site. The mononuclear complexes [Ru(bipy) 2 (Me 2 L 1 )][PF 6 ] 2 ( 1 ) and [Ru(bipy) 2 (H 2 L 1 )][PF 6 ] 2 ( 2 ), were prepared and attachment of a second metal fragment to the pendant catechol site of 2 afforded the dinuclear complexes [(bipy) 2 Ru(μ-L 1 )PdL][PF 6 ] 2 ( 3 , L = bipy;
摘要4-甲基-4'-1-(3,4-二甲氧基苯基)-乙烯-2-基} -2,2'-联吡啶(Me 2 L 1)的甲氧基脱甲基提供了新的桥联配体H 2 L 1 [4-甲基-4'-1-(3,4-二羟基苯基)-亚乙基-2-基} -2,2'-联吡啶],其含有与2a儿茶酚结合位点。制备了单核络合物[Ru(bipy)2(Me 2 L 1)] [PF 6] 2(1)和[Ru(bipy)2(H 2 L 1)] [PF 6] 2(2)。将第二个金属片段连接到2的邻苯二酚侧链上,得到双核配合物[(bipy)2 Ru(μ-L1)PdL] [PF 6] 2(3,L = bipy; 4,L = 4,4 ′-t B u 2 -bipy),[(bipy)2 Ru(μ-L1)Pt(PPh 3)2] [PF 6] 2(5),[(bipy)2 Ru(μ-L1) Ru(NO)(Cp *)] [PF 6] 2(6)和[(bipy)2
