Benzylidene-bis(tricyclohexylphosphine)dichlororuthenium Usage And Synthesis
  • Chemical Propertiesbright purple powder
  • Usessuzuki reaction
  • UsesCatalysis of olefin metathesis including ring-closing of dienes, cross metathesis and ring-opening methathesis polymerizations (ROMP).
  • Purification MethodsWash it repeatedly with Me2CO and MeOH and dry it in a vacuum. Alternatively dissolve it in CH2Cl2, concentrate it to half its volume, filter, add MeOH to precipitate it as purple microcrystals. Filter these off, wash several times with Me2CO and MeOH and dry them in a vacuum for several hours. [Scwab et al. J Am Chem Soc 118 100 1996, Miller et al.
