Description

Application

Copper(I) chloride may be used in the following processes:

• Along with magnesium chloride, to catalyze the conjugate addition of organomagnesium reagents to α,β-ethylenic ketones to form 1,4-addition products.
• To facilitate the addition of an amine to a nitrile to form an amidine, which on reduction forms tertiary amine.
• To catalyze the reaction of olefinic hydrocarbons with phenyl selenocyanate to form β-alkoxyalkyl phenyl selenide.

Shows unique character as an initiator of radical reactions such as the hydrostannation of α,β-unsaturated ketones.
