The hydrogenation on Raney nickel of 3-alkenyl-substituted pyrazolines and also of 3-methyl-5-(2-furyl)-1H-pyrazoline and 3,3'-bipyrazoline afforded substituted 1,3-diaminobutanes, 1,3-diaminopentanes, 1,3-diaminohexane, and 1,3,4,6-tetraaminohexane. Under the same conditions from 3-acetyl-4-(2-furyl)-1H-pyrazoline 3-amino-2-methyl-4-(2-furyl) pyrrolidine was obtained.

carbon-palladium beta elimination, (4) rearrangement of the resulting unsaturated alkylpalladium compound to a π-allylpalladium compound by a series of reversible palladium hydride beta elimination and readdition steps, (5) anionformation by removal of a proton from the functional group present on the arene, and (6) nucleophillic substitution of the palladium by the resulting anion.
