说明

一般描述

Oxalic acid dihydrate (OAD) crystals are reported to be monoclinic with P2₁/n space group.[1] The electron density of OAD has been obtained using X-ray diffraction studies under high resolution.[2]

应用

Oxalic acid dihydrate may be used:

As a catalyst in the preparation of tetrahydroquinoline derivatives via imino Diels-Alder reaction.[3]
As a homogeneous catalyst in the preparation of highly functionalized piperidines via multi-component reaction.[4]
As an oxidant for the formation of triazolinediones from corresponding urazoles and bisurazoles via oxidation.[5]
In the transformation of thiols to nitrosothiols by reacting with sodium nitrite.[6]
