TITANOCENE BIS(TRIFLUOROMETHANESULFONATE) 화학적 특성, 용도, 생산

• 용도

  Catalyst for:
  
  • Transesterification
  • Stereoselective carbonyl-ene cyclization reactions
  • Sakurai reactions
  • Mukaiyama cross-aldol reactions
  
  Reactant for synthesis of heterobimetallic bridging dinitrogen complexes

• 제조 방법

  TITANOCENE BIS(TRIFLUOROMETHANESULFONATE) is prepared by treatment of a 0.06 M THF solution of Dichlorobis(cyclopentadienyl)titanium with 5.5 equiv of a 0.19 M THF solution of Silver(I) Trifluoromethanesulfonate. After stirring for 15 min the reaction mixture is filtered, the red filtrate is layered with hexane, and the resulting red crystals are collected. Recrystallization from CH2Cl2/pentane or THF/hexane affords Cp2Ti(OSO2CF3)2 (25-30%) as red needles.
