General description

The structure of copper(I) chloride is similar to zinc-blende crystal at room temperature; the structure is wurtzite at 407 °C and at higher temperatures it forms copper(I) chloride vapor as per mass spectroscopy.

Application

CuCl may be used as an initiator for hydrostannation of α,α-unsaturated ketones and other similar radical reactions.
Shows unique character as an initiator of radical reactions such as the hydrostannation of α,β-unsaturated ketones.
Shows unique character as an initiator of radical reactions such as the hydrostannation of α,β-unsaturated ketones.

Features and Benefits
