Abstract: A process has been provided for preparing perhalo nitroso alkanes from a halocarbon compound of the formula RCX2H wherein X is fluorine, chlorine, or bromine and R is a halogen or a perhalo radical and wherein the halogens substituents are fluorine, chlorine, or bromine. The process is carried out by reacting the halocarbon with nitrosyl chloride in a vapor phase at a pressure of one atmosphere or less and at a temperature from 160* C. and lower while irradiating the reaction mixture with radiant energy at the characteristic wavelength displayed by nitrosyl chloride.
