Reaction Conditions

Reaction Steps

To a 30 ml of flask equipped with distillating apparatus, 30 mg of conc. sulfuric acid, 10 ml of MIBK, 598 mg of p-hydroxybenzaldoxime were introduced and the reaction mixture was heated up to 130° C. Heating under stirring with a magnetic stirrer was continued for 30 minutes, and about 3.5 ml of MIBK thereby was distilled off. Reaction solution was subjected to gaschromatography analysis to find that 392 mg (76% yield) of p-cyanophenol was produced. The conversion was 100%.
