Abstract
Conditions necessary for the electrolytic preparation of p‐methoxyphenyl‐acetonitrile from α‐hydroxy‐p‐methoxyphenylacetonitrile and its esters were determined polarographically. Polarographic reduction waves were obtained in dioxane and water only in the presence of tetrabutylammonium iodide and tetramethylammonium iodide. Alpha‐benzoxy‐p‐methoxyphenylacetonitrile which was reduced at the most positive potential gave no reduction wave in the presence of either ammonium chloride or lithium chloride.On the basis of the ease of reduction and ease of preparation α‐benzoxy‐p‐methoxyphenylacetonitrile was used as the starting material in the large scale reduction at a mercury cathode and gave p‐methoxyphenylacetonitrile in yields averaging 65%.
