General description

Calcium chloride dihydrate is an inorganic compound that is commonly used as an environmentally friendly catalyst in organic synthesis. It is also used in asymmetric transformation reactions.

Application

Calcium chloride dihydrate can be used as a catalyst:      
  • In the asymmetric 1,4-addition and [3+2]-cycloaddition reactions in the presence of box-type ligands.      
  • To synthesize hexahydropyrimidine derivatives via a one-pot three-component condensation reaction of ethyl/methyl acetoacetate, aniline, and formaldehyde.

It can also be used as a calcium precursor to synthesize macro/mesoporous dicalcium phosphate monolith (CaHPO4) via the sol-gel method using phosphoric acid (H3PO4), and poly(acrylic acid) (PAA).
