Description

General description

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

Application

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.
