Chromyl chloride

It can also be prepared directly by exposing chromium trioxide to anhydrous hydrogen chloride gas.

No similar compound is formed in the presence of fluoride, bromide, iodide, or cyanide, making this test specific to chlorides.

Chromyl chloride oxidizes internal alkenes to alpha-chloroketones or related derivatives.

[5] It will also attack benzylic methyl groups to give aldehydes via the Étard reaction.

Chromyl chloride is severely corrosive and easily burns the skin and eyes.

NFPA 704 four-colored diamond Health 3: Short exposure could cause serious temporary or residual injury. E.g. chlorine gas Flammability 0: Will not burn. E.g. water Instability 2: Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water. E.g. white phosphorus Special hazard W+OX: Reacts with water in an unusual or dangerous manner AND is oxidizer
Chromyl chloride is often stored in sealed glass ampoules to prevent vapours leaking out of the container
