General description

Magnesium perchlorate (Mg(ClO4)2) is widely used as drying agent for gases. It can remove water from gases (with no organic contaminants) at the rate of 0.001mgwater/l.

Application

Magnesium perchlorate (Mg(ClO4)2) may be employed as a catalyst in the following studies:
  • Preparation of α-aminophosphonates.
  • Enantioselective Diels-Alder reaction between cyclopentadiene and 3-acryloyl-1,3-oxazolin-2-one.
  • Preparation of imines and phenylhydrazones.
  • Protection of alcohols in the form of t-butyl ethers.
Magnesium perchlorate may be used as a catalyst in the synthesis of the following compounds:
  • α-Aminophosphonates via three-component reaction between an amine, an aldehyde or a ketone and a di-/trialkyl phosphite.
  • Imines and phenylhydrazones by the condensation of carbonyl compounds with amines and phenylhydrazine.
  • Knoevenagel adducts via Knoevenagel condensation between β-diketones and aliphatic or aromatic aldehydes.
It may also be used to catalyze the protection of alcohols as t-butyl ethers.
