General description

Super-Hydride® solution (Lithium triethylborohydride or LiTEBH) is widely used as a powerful and selective reducing agent that shows super hydride activity in organic synthesis.

Application

LiTEBH can be used as a reagent:
  • To reduce alkyl halides to alkanes via dehydrogenation reactions.
  • For the selective reduction of epoxides to Markovnikov alcohols.
  • To reduce tosylates or mesylates primary alcohols to hydrocarbons.
  • For reductive cyclization reactions for the preparation of useful intermediates.
  • In the synthesis of hepta(manno-3-deoxy-6-O-t-butyldimethylsilyl)-β-cyclodextrin by reduction of hepta(manno-2,3-anhydro-6-O-t-butyldimethylsilyl)-β-cyclodextrin.
  • For hydrodefluorination of C-F bonds using Ni catalyst.
  • To prepare alkynyl alcohols from cleavage of cyclic keto-vinyl triflates.
  • In the stereoselective reduction of bicyclic imides, isoquinolines, and pyridines.
  • To prepare tungsten and molybdenum hydride complexes.
