Trimethylboroxine Chemical Properties,Usage,Production

  • Chemical Properties colorless to yellow solution
  • Uses Trimethylboroxine is used as a derivatizing agent for GLC analysis. It is used in a diverse array of areas, including as a polymerization additive. It is also used in the preparation of CBS catalysts for asymmetric reductions.?
  • Uses
    Trimethylboroxine (TMB) is a cyclic anhydride of methyl-boronic acid. It can be used as a:
    • Methylating agent for the methylation of various aromatic halides and C(sp3)?H bonds using palladium catalyst.
    • Reagent in the preparation of polymer supported CBS (Corey, Bakshi, and Shibata) catalysts.

  • Uses
    Trimethylboroxine (TMB) is a cyclic anhydride of methyl-boronic acid. It can be been used:
    • As a derivatizing agent for gas chromatographic/mass spectrometric analysis.
    • In the preparation of methylaluminoxane (MAO) which is used in the polymerization of olefins.
    • As an electrolyte additive to enhance the interface stability of electrode/electrolyte.
    • In methylation of aryl halides by palladium-catalyzed Suzuki-Miyaura coupling reaction.
    • In the preparation of CBS (Corey, Bakshi and Shibata) catalysts for asymmetric reductions of ketones to alcohols.

  • Application Trimethylboroxine (TMB) is a cyclic anhydride of methyl-boronic acid. It can be been used:
    As a derivatizing agent for gas chromatographic/mass spectrometric analysis.
    In the preparation of methylaluminoxane (MAO) which is used in the polymerization of olefins.
    As an electrolyte additive to enhance the interface stability of electrode/electrolyte.
    In methylation of aryl halides by palladium-catalyzed Suzuki-Miyaura coupling reaction.
    In the preparation of CBS (Corey, Bakshi and Shibata) catalysts for asymmetric reductions of ketones to alcohols.
  • Purification Methods Possible impurity is methylboronic acid. If present, then add a few drops of conc H2SO4 and distil it immediately, then fractionate it through an efficient column.
