    Abstract: Disclosed is the reaction of propylene with acrylonitrile or acrylamide to make a cyano- or amidopentene and reacting that compound with NH.sub.3 and O.sub.2 to form mucononitrile or 5-cyano-2,4-pentadiene amide. Also disclosed is a process which comprises contacting a reactant of the formula H--(CH.sub.2).sub.a --(CH.dbd.CH)--(CH.sub.2).sub.b X with oxygen and ammonia to thereby form a product of the formula NC--CH.dbd.CH--CH.dbd.CH--X wherein X is --CN or --CONH.sub.2 and each of a and b are zero or an integer from 1 to 3 such that a+b=3.

    Abstract translation: 公开了丙烯与丙烯腈或丙烯酰胺反应以制备氰基或酰胺基戊烯,并使该化合物与NH 3和O 2反应形成粘腈或5-氰基-2,4-戊二烯酰胺。 还公开了一种方法,其包括使式H-(CH 2)a - (CH = CH) - (CH 2)b X的反应物与氧和氨接触,从而形成式NC-CH = CH-CH = CH-X,其中X是-CN或-CONH 2,a和b各自为0或1至3的整数,使得+ b = 3。
