Competitive hydrogenation of alkenes (cyclohexene, hex-1-ene, hept-1-ene, oct-1-ene) and dienes (octa-1,7-diene, cyclohexa-1,3-diene) was carried out by catalytic hydrogen transfer from ammonium formate on palladium in methanol. The adsorptivity and reactivity of the hydrocarbons decreased in the series: cyclic diene > linear diene > linear 1-alkene > cyclic alkene.
