一般描述
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.
应用
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.

We have investigated the photosensitized monomerization of the cis,syn-cyclobutane dimer of 1,3-dimethylthymine using riboflavin tetraacetate and a 5-deazaflavin derivative as photosensitizer. Although little monomerization of the dimer is induced by photoexcitation of the flavins in the absence of any additives
