Copper-free click chemistry reaction
WebHer team has developed new click reactions, including copper-free versions, that avoid toxic side-reactions associated with the original click chemistry. These techniques are allowing researchers to study aspects of biochemistry that were previously inaccessible like processes involving the sugars attached to proteins. WebScience Chemistry Reaction 1: Elemental copper reacts with aqueous nitric acid to produce copper (II) nitrate, nitrogen dioxide gas, and hydrogen oxide (is this water?). • Reaction 2: Copper (II)nitrate reacts with sodium hydroxide to form copper (II) hydroxide and sodium nitrate. Copper (II) hydroxide is a blue, gel like solid.
