General description

Sodium tetraborate decahydrate is a naturally occurring material used as a catalyst or additive for many organic transformations such as Nef reaction, Knoevenagel condensation, substitution, addition, selective methylation of vicinal diols, and desilylation of trimethylsilyl alkynones.

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.
