General description
Application
- As an efficient and low-cost catalyst for the synthesis of 2-aminochrome by the reaction between aromatic aldehyde, malononitrile, and α- or β-naphthol under solvent-free conditions.
- As a buffer in the synthesis of cyclic, acyclic enones and α, β-unsaturated aldehydes from trimethylsilyl enol ethers by using palladium as a catalyst and oxone as oxidant.
- As an efficient catalyst in the synthesis of 3,4-dihydropyrano[3,2-c] chromenes from aldehydes, malononitrile and 4-hydroxycoumarin.
- As a phosphorous precursor with the phosphoric acid in the synthesis of hydroxyapatite by precipitation method using anionic surfactant SDS (sodium dodefcyl sulfate).
