Opis

General description

Zinc bromide is an inorganic salt. Zinc bromide supported on hydroxyapatite (Zn-HAP) promotes the synthesis of 3-substituted indoles.

Application

Zinc bromide (ZnBr₂) may be used for the following studies:

• Removal of dimethoxytrityl ethers from deoxynucleosides.[1]
• Removal of N-acyl protecting group in nucleoside derivatives.
• Alkylation of O-silylated dienolates of unsaturated ketones and esters.
• As catalyst in the synthesis of α-perfluoroalkylated homoallylic alcohols.
