Catalytic synthesis of 1,3-propylenediamines

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.
