Abstract
A synthetic study of ruthenium complexes containing pentafluorobenzenethiolato ligand is presented. The bis(triphenylphosphine) complex CpRu(PPh3)2SC6F5 (1) is prepared from CpRu(PPh3)2Cl and C6F5S− in high yield. This complex is readily reacted with CO gas to give the mixed carbonyl-phosphine complex CpRu(PPh3)(CO)SC6F5 (2) and with NOBF4 at room temperature to give [CpRu(PPh3)(NO)SC6F5]BF4 (3). The one-pot reaction of CpRu(PPh3)2Cl, dppa ligands, and C6F5S− produces CpRu(dppa)SC6F5 [dppa = bis(diphenylphosphino)methane: dppm (4); bis(diphenylphosphino)ethane: dppe (5)]. Complexes (1)–(5) have been characterized by spectroscopic techniques (i.r., 1H-n.m.r., 31P-n.m.r.) and by elemental analysis. The X-ray structural analysis of (5) is reported.
