Application
Sodium tetraborate decahydrate can be used as a catalyst in the:
-
Regioselective thiolysis of 1,2-epoxides by using thiols to synthesize β-hydroxy sulfides.
-
Hetero-Michael addition of thiols with electron-deficient olefins to synthesize corresponding β-adducts.
-
Solvent-free Biginelli reaction to synthesize 3,4-dihydropyrimidin-2(1H)-ones.
It can also be used as an additive to prepare polypyrrole-borax composites with high dielectric properties.
