Descrição geral

Nickel(II) chloride hexahydrate is a hydrated nickel salt. Its crystals were monoclinc and crystal structure was investigated by X-ray single crystal method.

Aplicação

Nickel(II) chloride hexahydrate may be employed as a catalyst in the high yield synthesis of tetra-substituted pyrrole derivatives. It may be used for the conversion of tetrahydropyranyl (THP) and tert-butyldimethylsilyl (TBS) ethers to the corresponding hydroxyl compounds.
Nickel(II) chloride hexahydrate may be used as a catalyst in the following processes:
  • Synthesis of tetra-substituted pyrrole derivatives via four-component condensation reaction of aromatic aldehydes, benzylamines, β-ketoesters and nitroalkanes.
  • In combination with 1,2-ethanedithiol for the deprotection of tetrahydropyranyl (THP) and tert-butyldimethylsilyl (TBS) ethers to their corresponding hydroxyl compounds.
  • Synthesis of 3,4-dihydropyrimidinones from aldehydes and β-keto esters via Biginelli condensation.
