Twenty nitriles, including saturated and unsaturated aliphatic, araliphatic, and aromatic nitriles, were prepared from the corresponding aldehydes, commonly used as flavors or fragrances. The aldehydes were converted to aldoximes first, which then underwent dehydration by treatment with oxalyl chloride in the presence of a catalytic amount of dimethyl sulfoxide. The nitriles were obtained in high yields in most cases. The odor characteristics of the nitriles obtained were evaluated by GC‐O. The nitriles present varied characteristic odors, which are usually distinct from those of the corresponding aldehydes.
