Catalytic liquid and vapor phase proceesea for the preparation of% butenenitrile from allyl chloride and hydrogen cyanide are described. Various sulfides were prepared by the free radical-catalyzed addition of thiols to 3-butenenitrile1 bbutenoic acid and esters, and were oxidized to the respective sulfones. Relative rates of isomerization of 3-butenenitrile to 2- butenenitrile using various amine catalysts were determined.
