prepared. Reaction of [Ru(PPh3)3Cl2] and equal equiv. of HL1 in tetrahydrofuran in the presence of triethylamine afforded complex [Ru(L1)(PPh3)2Cl] (1) with two triphenylphosphine ligands trans to each other. Treatment of HL2 with equal equiv. of [RuHCl(CO)(PPh3)3], [Ru(CO)2Cl2]n or cis-[RuCl2(DMSO)4] (DMSO = dimethylsulfoxide) gave complexes [Ru(L2)(CO)(PPh3)Cl] (2), [Ru(L2)(CO)2Cl] (3), and [Ru(L2)(DMSO)2Cl]
摘要O,N,S供体的三个三齿单阴离子席夫碱配体分别为3,5-二溴-N-(2-(甲基硫烷基)苯基)水杨醛亚胺(HL1),5-氯-N-(2制备了-(甲基硫烷基)苯基)水杨醛亚胺(HL2)和3,5-二叔丁基-N-(2-(甲基硫烷基)苯基)水杨醛亚胺(HL3)。[Ru(PPh3)3Cl2]与等当量的反应。在三乙胺存在下,于四氢呋喃中制备HL1,得到具有两个三苯基膦配体的反式的[Ru(L1)(PPh3)2Cl](1)配合物。等同处理HL2。[RuHCl(CO)(PPh3)3],[Ru(CO)2Cl2] n或顺式-[RuCl2(DMSO)4](DMSO =二甲基亚砜)的配合物得到[Ru(L2)(CO)(PPh3)Cl] (2),[Ru(L2)(CO)2Cl](3)和[Ru(L2)(DMSO)2Cl](4)。HL3与[Ru(CO)2Cl2] n,[Ru(COD)Cl2] 2(COD = 1,5-环辛二烯)之间的相互作用
