Application

Trimethyl borate can be used as:
  • A reagent in the preparation of various trialkylamine−boranes from corresponding trialkylamines using lithium hydride/aluminum chloride catalyst.
  • A source of boron in the synthesis of boron nitride (BN) nanotubes by thermal-heating chemical vapor deposition (TH-CVD) method.
  • An electrolytic additive for electrochemical applications.
  • A reagent along with lithium di-tert-butyl(2,2,6,6-tetramethylpiperidino)zincate (TMP-zincate) for the synthesis of 1-tert-butyl-3,4-dihydroisoquinoline from isoquinoline via ortho metalation reaction.
