V-60 (AIBN)

This white powder is soluble in alcohols and common organic solvents but is insoluble in water. It is often used as a foamer in plastics and rubber and as a radical initiator. In its most characteristic reaction, AIBN decomposes , eliminating a molecule of nitrogen gas to form two 2-cyanopropyl radicals:. These radicals can initiate free-radical polymerizations and other radical-induced reactions. For instance, a mixture of styrene and maleic anhydride in toluene will react if heated, forming the copolymer upon addition of AIBN. Another example of a radical reaction that can be initiated by AIBN is the anti-Markovnikov hydrohalogenation of alkenes. AIBN is produced from acetone cyanohydrin and hydrazine , then followed by oxidation: [1].
