Abstract
The present invention provides a process for making 3-hydroxyalkanenitriles comprising the steps of reacting an alkenylnitrile, wherein the alkenylnitrile is an alkenyl-2-nitrile or an alkenylnitrile which under reaction conditions isomerizes to form an alkenyl-2-nitrile, in the presence of a base with benzyl alcohol to form a 3-benzyloxyalkanenitrile adduct and then partially hydrogenating the adduct in the presence of a trace amount of HCl to form the 3-hydroxyalkanenitrile or fully hydrogenating the adduct to form a 3-hydroxyaminoalkane.
