Application
Trimethyl borate (TMB) can be used:
- For the synthesis of luminogens having triphenylamine core and tetraphenylethene peripheral moieties.
- For the synthesis of ammonia borane and trialkylamine boranes.
- In the reduction of carboxylic acids in the presence of borane-methyl sulfide.
- As a reagent to crosslink phopshate complexes.
- As a source of boron to synthesize boron nitride nanotubes by chemical vapor deposition (CVD) method.
