The addition of nitryl chloride to a number of unsaturated compounds has been reported in the lit~ ature.~ In many cases, the reaction is complicated by addition of the. elements of chlorine, Nz03 or Nz04 across the double bond, depending on the solvent used and the olefin studied. In the simple examples reported herein, all of these reactions have been observed, suggesting that nitryl chloride can easily disproportionate to chlorine and N204.
