應用

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.
