一般描述
Oxalic acid dihydrate (OAD) crystals are reported to be monoclinic with P21/n space 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.
