一般描述

Copper (II) oxide is one of the two stable oxides of copper. Cupric oxide is a precursor to many copper-containing products and chemicals. It is used as a pigment, fungicide, and antirust protection agent for marine paints. CuO possesses notable and admirable characteristics like abundance and affordability, ease of manufacturing, scalability, non-toxicity, antioxidant properties, and semiconducting characteristics.

应用

Copper (II) oxide is used:,As a catalyst in the synthesis of 2-Aryl- and 2-alkenyl-1,3,4-oxadiazoles from treating 1,3,4-oxadiazoles with aryl or alkenyl halides.
