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