Nitryl chloride is a volatile inorganic compound with formula ClNO2. At standard conditions it is a gas.

Formation

[edit]

Nitryl chloride can be formed in the reaction of dinitrogen pentoxide with chlorides or hydrogen chloride:[1][2]

N2O5 + 2HCl 2ClNO2 + H2O
N2O5 + NaCl ClNO2 + NaNO3

Reactions

[edit]

Nitryl chloride adds to olefins in a radical reaction.[3]
