Production and reactions

All three allylamines, mono-, di-, and triallylamine, are produced by the treating allyl chloride with ammonia followed by distillation.^[3] Or by the reaction of allyl chloride with hexamine.^[4] Pure samples can be prepared by hydrolysis of allyl isothiocyanate.^[5] It behaves as a typical amine.^[6]

Polymerization can be used to prepare the homopolymer (polyallylamine) or copolymers. The polymers are promising membranes for use in reverse osmosis.^[3]

Other allylamines

Diallylamine is a precursor to industrial products. Functionalized allylamines have pharmaceutical applications. Pharmaceutically important allylamines include flunarizine and naftifine; the latter spurred the development of Petasis' borono-Mannich reaction. Flunarizine aids in the relief of migraines while naftifine acts to fight common fungus causing infections such as athlete's foot, jock itch, and ringworm.^[7]

Flunarizine and naftifine are pharmacologically active allylamines.

Safety

Allylamine, like other allyl derivatives is a lachrymator and skin irritant. Its oral LD₅₀ is 106 mg/kg for rats.
