Description
General DescriptionOxalic acid dihydrate (OAD) crystals are reported to be monoclinic with P 2 1 / n space group. The electron density of OAD has been obtained using X-ray diffraction studies under high resolution.ApplicationOxalic 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
