General description

Zinc bromide is an inorganic salt. Zinc bromide supported on hydroxyapatite (Zn-HAP) promotes the synthesis of 3-substituted indoles.[1]

Application

Zinc bromide (ZnBr2) may be used for the following studies:
  • Removal of dimethoxytrityl ethers from deoxynucleosides.[2]
  • Removal of N-acyl protecting group in nucleoside derivatives.[3]
  • Alkylation of O-silylated dienolates of unsaturated ketones and esters.[4]
  • As catalyst in the synthesis of α-perfluoroalkylated homoallylic alcohols.[5]
