Abstract: A method of preparing nitrocycloalkanones by simultaneously contacting a solution containing a cycloalkene, a 2-pyrrolidinone denitrating agent and an organic solvent with a mixture of dinitrogen tetroxide and oxygen, the mole ratio of denitrating agent to cycloalkene being above 0.1:1 and up to about 2:1, preferably about 0.5:1 to 1:1, as a one step nitrooxidation reaction. The nitrocycloalkanones so formed are useful as fuel and lubricant additives as well as intermediates in the preparation of cyclic lactams such as caprolactam.

Abstract: Graft copolymers are prepared in a two-stage process by first reacting, for example, 1,2-polybutadiene or an ethylene/propylene/alkylidene norbornene terpolymer with dinitrogen tetroxide to form a nitrated backbone polymer having incorporated therein nitro and nitrite functions which serve, in the second stage of the process, as sites for the subsequent graft copolymerization of an acrylate monomer.

Abstract: A method of preparing alpha-nitroketones by simultaneously contacting a solution of an alkene, a denitrating agent and an organic solvent with a mixture of dinitrogen tetroxide and oxygen, the mole ratio of denitrating agent to alkene being above 0.1:1 and up to about 2:1, preferably about 0.5:1 and 1:1 as a one step nitrooxidation reaction. The alpha-nitroketones so prepared are useful as fuel and lubricant additives as well as intermediates in the preparation of amides, acids, and nitroalkanes.
