AbstractAddition of triphenylcyclopropenium bromide to the thiocarbonyl complex [RhCl(CS)(PPh3)2] affords novel bicyclic metalla‐3‐mercapto‐thiapyrylliums [Rh(κ2‐C,S‐C5S2Ph3)(PPh3)2X2] (X=Cl, Br) – heterocycles with no metal‐free isolobal precedent. Halide abstraction with silver triflate (AgOTf) in acetonitrile affords the salt [Rh(κ2‐C,S‐C5S2Ph3)(NCMe)2(PPh3)2Ag(OH2)2}Ag(OTf)3}]‐OTf which in turn reacts with sodium chloride to return [Rh(κ2‐C,S‐C5S2Ph3)(PPh3)2Cl2].
摘要在硫代羰基复合物[RhCl(CS)(PPh3)2]中加入溴化三苯基环丙烯,可得到新型双环金属-3-巯基-3-硫代吡啶鎓[Rh(κ2-C,S-C5S2Ph3)(PPh3)2X2](X=Cl,Br)--杂环,但没有无金属孤立硼的先例。在乙腈中用三酸银(AgOTf)萃取卤化物,得到盐[Rh(κ2-C,S-C5S2Ph3)(NCMe)2(PPh3)2Ag(OH2)2}Ag(OTf)3}]-OTF,再与氯化钠反应生成[Rh(κ2-C,S-C5S2Ph3)(PPh3)2Cl2]。
