一般描述

Oxalic acid dihydrate (OAD) crystals are reported to be monoclinic withP2₁/nspace group. The electron density of OAD has been obtained using X-ray diffraction studies under high resolution.

应用

Oxalic acid dihydrate may be used:

• As a catalyst in the preparation of tetrahydroquinoline derivatives via imino Diels-Alder reaction.
• As a homogeneous catalyst in the preparation of highly functionalized piperidines via multi-component reaction.
• As an oxidant for the formation of triazolinediones from corresponding urazoles and bisurazoles via oxidation.
• In the transformation of thiols to nitrosothiols by reacting with sodium nitrite.
