Descripción general

Application

Potassium disulfate (K 2 S 2 O 7 ) can be used: As a salt catalyst for the conversion of hemicellulose into reducing sugars such as xylose and galactose by mechanocatalysis . In the preparation of diacylbenzenes via Pd-catalyzed decarboxylative acylation of aromatic ketones with oxocarboxylic acids. As an oxidant for the preparation of monosubstituted triazoles from aryl azides and propargyl alcohol using Ag 2 O as a catalyst.
