In the case of the reaction of trans-2-hexenoic acid with acetonitrile it was established that acids of the olefinic series enter into trans-nitrilation with aliphatic nitriles; the reaction is complicated by thermal isomerization both of the initial acid and of the reaction products, i.e., the corresponding nitrile and N-acylamide.Under the conditions of the reaction of trans-2-hexenoic acid with deuteroacetonitrile-d3 1,3-hydride-deuteride shifts occur in the intermediate compounds (the N-acylamides).This leads to a redistribution of the deuterium atoms between the products of the investigated reaction.

Allyl β-oxo esters, allyl 1-alkenyl carbonates, and allyl α-cyano esters are converted into α,β-unsaturated ketones, aldehydes, and nitriles by palladium-catalyzed intramolecular decarboxylation-dehydrogenation.Palladium-phosphine complexes such as Pd(OAc)2-PPh3, Pd(OAc)2-dppe, or Pd2(dba)3*CHCl3-PPh3, are effective catalysts.Yields depend on solvents and on the mole ratio of palladium to phosphine.The optimum Pd/P ratio for each substrate was determined.Use of nitriles as solvents is essential for the dehydrogenation.
