설명

애플리케이션

Nickel(II) chloride can be used as a catalyst:

• To synthesize acyclic and cyclic dithioacetals via thioacetalization of aldehydes.
• To prepare α-aminonitrile derivatives via a one-pot, three-component coupling reaction of aldehydes, amines, and trimethylsilyl cyanide.
• In the hydrodefluorination of fluoroarenes in the presence of lithium triethylborohydride.
