New air-stable, water-soluble Ru(II)–phosphane complexes were synthesized in high purity by the reaction of cis-[RuCl2(dmso)4] with 2 equivalents of 1,3,5-triaza-7-phosphaadamantane (pta) and its N-methyl and N-benzyl derivatives (pta-Me and pta-Bn, respectively). All new complexes were characterized by elementary analysis and spectroscopic methods (NMR, ESI-MS) and the molecular structures of cis

生物(分别为pta-Me和pta-Bn)。所有新的配合物均通过元素分析和光谱法(NMR,ESI-MS)以及顺-顺-反-[RuCl 2(dmso)2(pta)2 ],顺-顺-反-[RuCl ]的分子结构进行了表征。2个(dmso)2(pta-H)2 ] Cl 2(在酸性溶液中获得)和顺式-顺式-反式-[RuCl 2(dmso)2(pta-Me)2 ](CF 3 SO 3)2是通过单晶X射线衍射测定。 在温和的条件下,顺式-[RuCl 2(dmso)4 ]以100%的选择性积极催化
