Mixtures of dinitrogen tetroxide and halogens have been shown to react mith olefins to produce compounds with a halogen atom on one carbon atom and a nitrogen-containing group on the other carbon atom of the original double bond. The nitrogen-containing group is-OXO2 when the olefin is ethylene itself or ethylene substituted with electron-supplying groups such as alkyl or acetoxy. It is--NO2 when the olefin is ethylene substituted with ...
