Abstract
2-Methyl-3-butenenitrile is efficiently and readily converted into a linear pentenenitrile, notably 3-pentenenitrile, a valuable intermediate for the production of adiponitrile, by isomerizing same in the presence of a catalytically effective amount of an aqueous solution of at least one sulfonated phosphine and at least one transition metal compound.
