研究了配位不饱和的钌杂s-顺丁二烯化合物[Ru(CHC(PPh3)CH(2-Py))Cl2PPh3]BF4(1)与水、甲醇、苯胺和2-巯基吡啶等亲核试剂的[4+1]关环反应,合成了一系列有趣的钌杂多环化合物[Ru(CHC(PPh3)CHR(2-Py))Cl(PPh3)2]BF4[R=OH(2),OMe(3),和NHPh(4)]与[Ru(CHC(PPh3)CH(S(2-Py))(2-Py))PPh3(S(2-Py)]BF4(5).此外,将配位不饱和的钌配合物1与三苯基膦配体反应,制备了类似于氮杂金属萘的配位饱和化合物[Ru(CHC(PPh3)CH(2-Py))Cl2(PPh3)2]BF4(6).6与HBF4反应可生成金属杂环结构类似的分子内含三氯桥的双钌核配合物[{Ru(CHC(PPh3)CH(2-Py))PPh3}2(μ-Cl)3](BF4)3(7).以上产物均通过核磁(NMR)与元素分析进行了表征,并解析了部分产物的X射线单晶结构.
The coordination between Ru (CHC (PPh3) CH (2-Py)) Cl2PPh3] BF4 (1) and nucleophiles such as water, methanol, aniline and 2-mercaptopyridine A series of interesting ruthenium heteropolycyclic compounds [Ru (CHC (PPh3) CHR (2-Py)) Cl (PPh3) 2] BF4 [R = OH , OMe (3), and NHPh (4)] with [Ru (CHC (PPh3) CH (S (2-Py)) (2-Py)) PPh3 , A complex saturated compound [Ru (CHC (PPh3) CH (2-Py)) Cl2 (PPh3 ) 2] BF4 (6) .6 The reaction with HBF4 can generate a double ruthenium nucleus complex [{Ru (CHC (PPh3) CH (2-Py)) PPh3} 2 (μ-Cl) 3] (BF4) 3 (7) .The above products were characterized by NMR and elemental analysis, and the X-ray single crystal structure of some products was analyzed.
