Description
- 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.
